Question

Omar earns $10 per week for his allowance,

plus $25 for each lawn he mows. He wants
to earn at least $105 each week: How
many lawns must Omar mow to meet his
weekly goal? Write and solve an inequality
to answer the question.

Answer 1

25x + 10 ≥ 105

He needs to mow at least 4 lawns per week.

Explanation:

At least $105 means equal to or greater than $105.

Let the number of lawns = x.

He earns $25 per lawn so for x lawns he earns 25x.

He also earns $10 per week.

Total earnings per week = 25x + 10

Inequality:

25x + 10 ≥ 105

25x ≥ 95

x ≥ 3.8

He needs to mow more than 3.8 lawns per week.

Since he can only mow complete lawns, he needs to mow at least 4 lawns per week.
