Kevin is saving for a new bike. He has already saved $65. He makes $15 for each lawn that he mows. The bike that Kevin wants to buy costs $175. Which inequality could be used to find x, the number of lawns Kevin needs to mow to earn enough money to buy the bike he wants?

175=15x+65
X is the number of lawns Kevin has to mow.

Amount already Kevin has = $65

Amount he is paid for mowing a lawn = $15

The total cost of the Bike Kevin wants to purchase is $175

Now if x is the number of lawns Kevin needs to mow and if he is getting $15 per lawn.

Then the total amount received by Kevin for mowing the lawns shall be 15x.

So the total money Kevin shall have after mowing x lawns shall be 15x + 65.

But he needs at least $175

So

15x + 65 ≥ 175

Hence inequality 15x + 65 ≥ 175 could be used to find x, the number of lawns Kevin needs to mow to earn enough money to buy the bike he wants.
