Earl mows lawns one weekend. He earns $12 for each lawn that he mows. He spends $40 on gas and other supplies.

What function equation represents Earl's profit from mowing x lawns?

f(x)=40x+12f(x)=40x+12

f(x)=40x−12f(x)=40x−12

f(x)=12x−40f(x)=12x−40

f(x)=12x+40

the correct answer would be:
f(x)=12x−40f(x)=12x−40

Hope this helps

Answer:

The Earl's profit from mowing x lawns is represented by

f(x) = 12x−40

Reason

As given

Earl mows lawns one weekend.

He earns $12 for each lawn that he mows.

He spends $40 on gas and other supplies.

As given the numbers of lawns are represented by x.

Than the cost for mowing x lawns = 12x

Thus

Profit =  The cost for mowing x lawns  -  spends money on gas and other supplies

f(t) = 12x - 40

Therefore the profit from mowing x lawns is  f(t) = 12x - 40 .
