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

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.

If ScoTT earns $25 per week

$25*20 = $500

but due to the initial investment, the final earns will be

$500 - $250 = $250
