Question

Melissa earns $180 a week selling shoes plus a commission of $10 each pair of shoes she sells. How

many pairs of shoes must she sell to make a minimum of $500 a week?

Answer 1

Explanation:

10X+ 180= 500

10X= 500-180

10X= 320. .....divine both sides by 10 to solve for X

X = 32.

check

10(32)+180 = 500

320+180 =500

500 =500...confirmed
