Question

Courtney must earn at least $150 to pay for broken window. She earns $10 for every car she washes.

Answer 1

Answer:

10c ≥ 150

At least 15 cars (or c ≥ 15)

Step-by-step explanation:

If she gets $10 for every car she washes a car then 10c is the rate of her gaining money and she needs at least (greater than or equal to) $150.

This equation can be used to express the situation:

10c ≥ 150

To solve you divide the 10 from both sides of the inequality to get.

c ≥ 15
