David begins the summer with a savings of $54.00 more than Fatima. David’s job
pays $8.25 per hour. Fatima’s job pays $9.75. If they both work the same amount of
time each day, how many hours of work will it take David to have as much money as
Fatima? Write an inequality and then solve.
Answer:
36 hours (1 1/2 days, 351$ )
Step-by-step explanation:
create a linear system and solve.
8.25x + 54 = 9.75x
_______________
-8.25x -8.25x
_______________
54 = 1.5x
_______________
1.5 x = 54
_______________
÷ 1.5. ÷1.5
_______________
x = 36.
if you want to know how much money they will have at this time, just substitute the x value that you solved for back into the equation
x = 36 -> 8.25(x) + 54 = 9.75(x)
8.25(36) + 54 = 9.75(36)
297 + 54 = 351
351 = 351
________________________________
David's budget >= 54$
Fatima's budget >= 0$
The required inequality is 8.25x + 54 = 9.75x
It will take 36 hours for David to have as much as Fatima.
David :
Initial saving = 54
Pay per hour = $8.25
Fatima :
Pay per hour = $9.75
Let number of hours worked = x
David's total = $8.25x + 54
Fatima's total = 9.75x
In other to have the same amount :
8.25x + 54 = 9.75x
Collect like terms :
8.25x - 9.75x = - 54
-1.5x = - 54
x = - 54 / - 1.5
x = 36
Hence, it will take 36 hours for David to have as much as Fatima.

Max is a real estate agent and receives 2% commission on the first $400 000 and 1.5% on the value thereafter.
Find his commission for selling a property worth $920000. Please help me.
Answer:
commission = 15800
Step-by-step explanation:
920000 - 400000 = 520000
400000 x .02 = 8000
520000 x .015 = 7800
8000 + 7800 = 15800
Ron is saving money for college. Each month he deposits 10% of his net income plus
an additional $50 into a savings account. His net income, after taxes have been taken
out, is 80% of his gross income. Find the amount that Ron saves a month when his
gross income is $2400.
Answer:
$242
Step-by-step explanation:
His Gross income a month is $2400.
Now, we are told that his net income, after taxes have been taken out, is 80% of his gross income.
Thus;
Net income a month = 80% × 2400 = $1920
Now, Each month he deposits 10% of his net income plus an additional $50 into a savings account.
This means amount saved each month is = (10% × 1920) + 50 = 192 + 50 = $242

You are trying to find the distance AB between two points on either side of a river. You
measure the following distance:
Answer:32ft
Step-by-step explanation: I missed this as well, ED and AB are the same and if you don’t read you skip over the fact ED equals 32ft. Since ED and AB equal eachother it would be 32ft
The value of AB = 32 feet
What is congruency ?Congruent shapes are shapes that are exactly the same. The corresponding sides are the same and the corresponding angles are the same.
Given:
EC= 32 ft = BC
DC= 28 ft =AC
<ECD= <BCA
So, In ΔECD and ΔBCA
EC = BC
DC= AC
<ECD= <BCA
Thus, by SAS ΔECD ≅ ΔBCA
Hence, by CPCT : ED= BA = 32 ft.

· The senior class is planning an end of the year party to celebrate graduation. Their
total budget for food and drinks is $600. Each plate of food costs $5, and each drink
costs $1. Each person at the party gets one plate of food and one drink, with none
leftover. How many people went to the party?
Solve problem using systems of equations.
Answer:
100
Step-by-step explanation:
Because everyone had one plate and one drink, we can combine those individual prices.
5 + 1 = 6
Now we divide 600, the total cost, by 6, the cost for one person.
600 ÷ 6 = 100
So now we know that 100 people went to the party, as there was nothing left over.

I need help! The 20% off sale is a better deal than the $200 rebate or $150 coupon for the $1,500 dining room set. Explain why this is the best deal for them. Are they under budget?
Answer:
See explanation
Step-by-step explanation:
The 20% off sale is a better deal because 20% off of $1500 will cost $1200. (See work).
However, the 200 or 150 dollars off will cost $1300-1350. Thus, the better deal for the dining room set is to use the 20% off.
If their budget is $1250, they will be $50 under budget because they would be paying $1200 for the set.
Work:
1500 x 20%
1500 x 0.20 = 300
1500-300= $1200
1500-150= 1350
1500-200= 1300
Yes, the Porters are under budget. The 20% off sale is the best deal because $1,500 times 0.20 is $300. $300 is a bigger discount than the $150 coupon and $200 rebate. $300 off $1,500 is $1,200, which is less than the amount budgeted.

The length of a football field including the end zones is 48 feet longer than four times the length of a tennis
court. It is also 282 feet longer than a tennis court.
How long is the foorball field?
How long is the tennis court?
Answer:
T=78 feet (Tennis court)
360 feet (Football Filed)
Step-by-step explanation:
4T+48 = T+282
The length of the football field is 360 feet.
The length of the tennis court is 78 feet.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The length of a football field including the end zones is 48 feet longer than four times the length of a tennis court.
And, It is also 282 feet longer than a tennis court.
Let the length of the tennis court = x
So, The length of the football field = 48 + 4x
Here, The length of the football field is 282 feet longer than a tennis court.
So, We get;
⇒ 48 + 4x = 282 + x
⇒ 4x - x = 282 - 48
⇒ 3x = 234
⇒ x = 78
Thus, The length of the football field = 48 + 4x
= 48 + 4×78
= 48 + 312
= 360 feet
The length of the tennis court = x
= 78 feet
