Answer:

7.65 + 2.50h

Step-by-step 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

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