Question

Devin has started a lawn-care service. He will charge a mowing fee of $15 plus $2 per square yard of lawn. He also offers trimming service, at $10 plus $1 per yard of the perimeter. Using x for the length of the lawn and y for the width of the lawn, which part of the expression represents the charge for the mowing?

Answer 1

Mowing would be 2xy +15 I think this is what they are looking for.

It would be 2xy + 2x + 2y + 25 for everything

Answer 2

15 + 2xy is the expression represents the charge for the mowing

Explanation:

He will charge a mowing fee of $15 plus $2 per square yard of lawn.

Let x be the length of the lawn

y be the width of the lawn

Area of the lawn = length * width

Area = x*y square yards

Given that $2 per square yard

charge of mowing xy square yards = 2xy

Fixed charge is $15 so we add 15 as well

Expression becomes 15 + 2xy
