Tara mows lawns as a summer job. She

charges $9.50 for each lawn plus $2.50 for

every hour she works. The gasoline she needs

to mow an average lawn costs $1.85. Write an

expression for the profit Tara makes from

cutting a single lawn.

7.65 + 2.50h

Explanation:

The original expression for finding her profit is:

($9.50x + $2.50h) - 1.85x

x being the number of lawns she mows

h being the number of hours she works

If she were to only mow one lawn, the expression would be:

($9.50 (1) + $2.50h) - 1.85 (1)

h remains constant because we do not know the number of hours she works for

The above expression simplified:

($9.50 + $2.50h) - 1.85

So, I do ... $9.50 - 1.85 to get ...

$7.65 + $2.50h

9.50 + (2.50x) 1.85

Explanation:

I think this might be it because you don't really get the time she works for a lawn
