Suzanne earns $300 per week plus $15 per sale at her job. She is hoping to make AT LEAST $600 this week. How many sales will she need to make? Suzanne writes the inequality 15x+300≥600

, where x = the number of sales. Solve the inequality

A.x≥60
x is greater than or equal to 60

B.x≥20
x is greater than or equal to 20

C.x≥4500
x is greater than or equal to 4500

D.x≥1.95
x is greater than or equal to 1 point 9 5

1 answer

To solve the inequality 15x + 300 ≥ 600, we need to isolate x.

First, subtract 300 from both sides of the inequality:
15x + 300 - 300 ≥ 600 - 300
15x ≥ 300

Next, divide both sides of the inequality by 15:
(15x) / 15 ≥ 300 / 15
x ≥ 20

So, the correct answer is B. x ≥ 20.
