Angela paints a wall that has an area of 42 2/3 square yards.
She uses 1 1/3 gallons of paint.

Part A
What is Angela’s rate of paint coverage in square yards per gallon?


square yards per gallon.

Part B
The label on the paint container states that its average coverage rate is 275 square feet per gallon.
What is the difference in square feet per gallon between Angela’s rate of paint coverage and the average rate indicated on the label on the container?

(Note: 1 square yard = 9 square feet )


square feet per gallon difference.

Part A: 32 square yards per gallon

Part B: 13 square feet per gallon difference

Step-by-step explanation:

Part A:

To find how many square yards each gallon covers, you have to divide 42 2/3 by 1 1/3, which equals 32. That means each gallon of paint covers 32 square yards.

Part B:

First, you have to convert how much Angela covered in square yards to square feet. Since one square yard is equal to 9 square feet, we have to multiply 32 by 9, which equals 288. To find the difference, you have to subtract 288 - 275, which equals 13.
