Question

you want to paint the walls of your bedroom. Two walls measure 19 ft by 9 ft, and the other two walls measure 14 ft by 9 ft. The paint you wish to purchase costs $17 per gallon, and each gallon will cover 400 ft2 of wall. Find the total amount you will spend on paint.

Answer 1

total area = (19)(9) + 14(9) ft^2
= 297 ft^2

number of cans needed = 297/400 = .7425
Assuming you are buying the paint only by the gallon, you will have to buy 1 gallon, so the cost will be $17.00

btw, time to update that textbook, paint at $17 a gallon ????
