Carl has already earned $60 mowing lawns. He earns $15 per lawn. He needs at least $115 for a new string trimmer. Write and solve an inequality to determine how many more lawns Carl will need to mow to have at least $115. Carl needs to mow at least lawns to have at least $115.

Step-by-step explanation:

Carl's total Net Worth, y, would be the sum of what he already has ($60) plus any future payments for lawn care.  The total of these future payments would be $15x, where x is the number of lawns he mows for $15.

Total Net Worth, y = $60 + $15x

We could use this formula to calculate the number of lawns it will take for Carl to become a millionaire.  But Carl's most immediate goal is to have $115 to purchase a new string trimmer.

The inequality he must solve to determine how many lawns he needs to mow is:

$115 ≤ $60 + $15x

===

Solve this to find the number of lawns:

$55 ≤  $15x

3 ≤  x

or x ≥ 3 to have at least $115
