Moche started a summer business of mowing lawns. However, before he could mow lawns, he needed to purchase supplies (a lawnmower among other needs). Moche spent $395 gathering necessary materials. He makes on average $60 per lawn, mowed. Write an equation to show Moche his earnings for L lawns mowed.

• m = 60L - 395

• m = 60L + 395

• m = 60 - 395L

• m = 60 + 395L
