Question

2 Charles is saving $5 each week from his allowance. He already saved $15 from the money he earned from mowing his neighbor's lawn. Write the inequality to represent the number of weeks (w) will he need to save in order to save at least $75? (You are not solving this inequality.)​

Answer 1

15 + 5w ≥ 75

Explanation:

Let the number of weeks be represented as w.

We are told from the question that:

Charles is saving $5 each week from his allowance. He already saved $15 from the money he earned from mowing his neighbor's lawn.

The word "at least" in mathematics means equal to or greater than and it is represented by the sign ≥

Therefore, our inequality equation is written as:

15 + 5w ≥ 75
