Question

Your weekly base salary is $150. You can earn $20 for each cell phone that you sell. A. What is the minimum amount you can earn in a week? B. Write and solve an inequality that represents the number of cell phones you must cell to make at least $630 a week.

Answer 1

A.  The minimum amount is $150 if you sell no phones.  
B.  150 + 20x = 630 
Subtract 150 from both sides and you get
20x=480

Divide both sides by 20 to get x=24 

X= the number of cell phones needed to make $630 a week so you would need to sell 24 cell phones

Answer 2

150+20x ≥ 630. Hope this helped.
