Answer:

Step-by-step explanation:

Let the number of cell phones be represented by X;

Price per cell phone = $20

$150 is a constant

Minimum goal per week = $630

The inequality will be;

150 + 20X [tex]\geq[/tex] 630

20X [tex]\geq[/tex] 630 -150

20X [tex]\geq[/tex] 480

Divide both sides by 20 to solve for X;

X[tex]\geq[/tex] 480/20

X [tex]\geq[/tex] 24

Therefore, you must sell at least 24 cell phones.
