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?

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

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
