Question

Scott spends $250 for a lawn mower, but earns $25 a week mowing lawns. How much profit will he have after 20 weeks?

A.
$225
B.
$500
C.
$25
D.
$250

Answer 1

if ScoTT earns $25 per week
$25*20 = $500

but due to the initial investment, the final earns will be
$500 - $250 = $250

Answer 2

By mowing lawns, in 20 weeks he will earn:
20*25 = $500

Since he invested $250 in lawn mower his profit is equal to:
500-250= $250
In order to have profit Scott first needs to repay the price of lawn mower. Once he does that he will start making profit.
