It could be $4.25 per foot if it came of a standard roll, but then I would need to know the width of the roll, which you haven't given.
Area of the room = (15-ft x 14-ft) = 210 square feet
Area of the closet = (4-ft x 8-ft) = 32 square feet
Total area = (210 + 32) = 242 square feet.
Total cost of carpet = (242 x $4.25) = $1,028.50 plus pad and installation.
=========================================
You know what ? I think you may have mis-copied the price of carpet altogether.
At $4.25 per square foot, that's awfully expensive carpet.
I suspect the actual price is $4.25 per square yard. That's pretty cheap, but
it's a lot closer to reasonable than $4.25 per square foot is ($38.25 per yd² !)
If it's $4.25 per square yard, then we need to know that 1 square yd = 9 square ft.
The total requirement is 242/9 = 26 and 8/9 square yard, so you'll buy 27 sq yds.
$4.25 x 27 = $114.75 plus pad and installation. That sounds cheap but better.

Answers
Answer:
$48.87
Step-by-step explanation:
Let the deposited amount between the March 15th and the March 20th be x
Balance on 15th march = $56.75
The bank returned all the cancelled checks but too. One check was for $5 and the other was for $13.25
And he also deposited x amount
After deposits and deductions
So, balance = 56.75 +x - (13.25+5)
The new balance on 20th march = $87.37

Hence Carlos deposited $48.87 in his account between the March 15th and the March 20th.
Add: Deposit x
Less: Outstanding check 18.25 ⇒ 5 + 13.25
March 20 balance: 87.37
56.75 + x - 18.25 = 87.37
x = 87.37 - 56.75 + 18.25
x = 48.87 CHOICE D.
Outstanding checks are issued checks that are not yet deducted from the account.

Given:
Let x be the price of the pizza
$5 for the coupon
15% discount
Solution
x is the price of the pizza. If coupon is applied before:
(x-5)0.85=0.85x-0.85*5
if it is applied after: 0.85x-5
Therefore, the difference between the two is 0.15*5=0.75
The answer is USD 0.75
