Suzie 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? Suzie writes the inequality 15x + 300 > 600 where x equals the number of sales to help figure this out. Solve her inequality.
To solve the inequality, we need to isolate the variable x by performing inverse operations.
Starting with the original inequality:
15x + 300 > 600
Subtract 300 from both sides of the inequality:
15x + 300 - 300 > 600 - 300
15x > 300
Divide both sides of the inequality by 15 to isolate x:
(15x)/15 > 300/15
x > 20
Therefore, Suzie will need to make more than 20 sales to earn at least $600 this week.
