Mr.Lin is a telemarketer for a carpet-cleaning service. He is paid $100 per week plus $5 for every customer he brings in. If he wants to make $300 or more this week, How many customers does he needs to bring in?

Respuesta :

Answer:

He must bring in 40 or more customers.

Step-by-step explanation:

Let x represent the number of customers that he brings in.

He is paid $100 per week plus $5 for every customer he brings in. This means that if he brings in x customers in a week, the expression for the total amount that he would make is

100 + 5x

If he wants to make $300 or more this week, the expression would be

100 + 5x ≥ 300

5x ≥ 300 - 100

5x ≥ 200

x ≥ 200/5

x ≥ 40
