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
