Jacqueline has two part-time jobs. She earns $15 per hour, l, working as a lab assistant, and $12 per hour, s, working as a cashier. This is modeled by 15l+12s. Evaluate for l=5 and s=7 to find how much money Jacqueline will earn at her two jobs this week.
To find the total amount of money Jacqueline will earn this week, we need to substitute the values l=5 and s=7 into the expression 15l+12s and evaluate the result. This gives us 15*5+12*7=75+84=159. Therefore, Jacqueline will earn a total of $159 this week from her two part-time jobs.
Jacqueline will earn $159 at her two jobs this week.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given;
Jacqueline has two part-time jobs.
She earns $15 per hour, l, working as a lab assistant, and $12 per hour, s, working as a cashier.
This is modeled by 15l+12s.
We have the expression,
15l + 12s
To find the value of the expression:
Substitute the value of l and s to the expression.
We have l = 5 and s = 7.
So,
15(5) + 12(7)
= 75 + 84
= 159
Therefore, she will earn $159.

K-Mart is open Monday through Saturday from 8:00 AM to midnight and Sunday from 10:00 AM to 8:00 PM. How many hours is it open in one week
Answer:
106 hours
Step-by-step explanation:
K-Mart is open Monday through Saturday from 8:00 AM to midnight and Sunday from 10:00 AM to 8:00 PM. How many hours is it open in one week?
24:00 - 8:00 = 16:00 (16 hours) per day Monday to Saturday
16:00 * 6 = 96:00 (96 hours) total Monday to Saturday
20:00 - 10:00 = 10:00 (10 hours) Sunday
96:00 + 10:00 = 106:00 (106 hours) total
Leandro has four cubes like this one: He sticks them together to form the solid shown here and paints it blue all over. A week later, he separates the four cubes. What fraction of the total number of faces is WHITE?
Answer:
Step-by-step explanation: Each cube has a total of 6 sides. In the model, the top cube has 1 "hidden" side/1 side that is not exposed to the paint, the bottom middle has 1 "hidden" side, the right bottom cube has 1 "hidden" side, and so does the left. Adding up all the sides that are not exposed to the paint, there is a total of 4 white sides.

for any of the pet sitting services listed in the table, how many hours can you purchase before it would be cheaper to pay for one day.
Table if you need it
Number of pets =
One dog = $20 per day and $7 per hour
Two dogs = $25 per day and $9 per hour
One or Two Cats = $15 per day and $6 per hour
The amount i found for the recent question was $44
Answer:
One dog= 2 hours
Two dogs= 2 hours
One or Two cats= 2 hours
You would only be able to purchase 2 hours before it would be cheaper to pay for one day
Step-by-step explanation:
One dog: the hourly rate is $7
7x2 = $14 but 7x3 = $21
The daily rate is $20 so it would be cheaper to pay for the day after 2 hours.
Two dogs: the hourly rate is $9
9x2= $18 but 9x3= $27
With the daily rate being only $25, paying for anymore than 2 hours would be more expensive than paying for the day.
One or Two cats: the hourly rate is $6
6x2= $12 but 6x3=$18
Again, $18 is more than the daily rate of $15
You can purchase 2 hours before it would be cheaper to pay for one day.

Answer: $1.43
Step-by-step explanation: So, first you have to add his total bill (before taxes and the take-out) which is $8.33, then you add the fruit salad price ($2.99), and the tax ($2.25). You should get $13.57. Then, since he has the $10 & 5 dollar bills, you add that together to get $15. ($15.00) Now, subtract 13.57 from 15.00, and you should get $1.43 as the change. I hope this explanation helped.

Ten mangos and twelve avocadoes cost $23. Five mangos and four avocadoes cost $10. How much do one mango and one avocado cost?
Answer:
$2.15
Step-by-step explanation:
Let mango be m
Let avocado be a
10m + 12a = 23
5m + 4a = 10
Let's get rid of the mangos in the second equation
10m + 12a = 23
-2 x (5m + 4a = 10)
Now we get:
10m + 12a =23
-10m -8a = -20
Add both the equations and we get:
4a = 3
a = $0.75
since we know that one avocado is for $0.75, we can use this value to find the cost of one mango.
5m + 4a = 10
5m + 4(0.75) = 10
5m + 3 = 10
5m = 7
m = 1.4
So, we now know that a mango cost $1.4
To find the cost of one mango and one avocado:
a + m = 0.75 + 1.4 = 2.15
Therefore, the cost of one mango and one avocado is $2.15
The required cost of one mango is 1.4 and cost of one avocado is 0.75.
What is an equation ?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
Cost of ten mangos and twelve avocados is $23,
And cost of five mangos and four avocados is $10.
Let cost of mangoes be represented as M and cost of avocados be represented as A,
The equation can be written as,
10 M + 12 A = 23 (1)
5 M + 4 A = 10 (2)
By solving equation (1) and (2),
M = 7/5 = 1.4
N = 3/4 = 0.75
The cost of one mango is 1.4 and cost of one avocado is 0.75.

An accountant charges a fee of $120 to complete a company's taxes. The accountant also charges an additional $40 per hour to complete the taxes. Which of the following equations can be used to describe this problem?
y = 40 + 120x
y = 40 − 120x
y = 120 + 40x
y = 120 − 40x
Answer:
y = 120+ 40x
Step-by-step explanation:
The $40 is the rate of change meaning that that would be the number that is next to the variable and the 120 is just staying there meaning it does not have a variable.
if accountant also charges an additional $40 per hour to complete the taxes then the equation y = 40 + 120x can be used to describe.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The fixed fee of $120 is represented by the constant term in the equation, and the additional fee of $40 per hour is represented by the coefficient of x.
As the number of hours worked by the accountant increases, the total fee also increases at a rate of $40 per hour, hence the linear equation.
The equation that can be used to describe the accountant's fee is:
y = 120 + 40x
In this equation, y represents the total fee, and x represents the number of hours worked by the accountant.
Hence, if accountant also charges an additional $40 per hour to complete the taxes then the equation y = 40 + 120x can be used to describe.
