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.
Shutting the car door I caught a familiar scent. Suddenly, it was summer and I was nibbling cookies in my aunt's old truck. Every year we'd head out for an adventure on our way to see cousins. My aunt would drive until she was bleary-eyed, belting out songs with the radio. I hummed a familiar tune and thought about her chocolate chip cookies. I haven't taken a road trip for a long time!

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.
