Question

Omar mows lawns for $9.25 an hour. He spends $7.50 on gas for the mower. How much does he make if he works h hours?

Answer 1

It depends how many hrs it take for him to mow a lawn. For example, if he worked 3 hours on a lawn he would get 27.75 or 9.25 times 3. Minus 7.50 = 20.50

Answer 2

amount earned=amount earned per hour times time (h)
minus the cost for gas to find the end

so amount earened per hour is 9.25
h=time
and 7.5=amount spent

so

moneymade=9.25h-7.5
