Question

A salesperson earns $1000 a month plus a commission of 20% of sales. Find the minimum

amount of sales needed to receive a total income of at least $5000 per month. (Write
an inequality and solve.)

Answer 1

5000

Explanation:

1000+0.8s < 5000

subtract 1000 from both sides of the inequality

0.8s < 4000

divide both sides by 0.8 to get the number of sales (s)

s <5000
