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

OleMash [197]

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

Kaylis [27]

15 performances can be accommodated

Solution:

Given that,

Each performer for the talent show has 7 minutes for his or her performance

The introduction for the talent show is 25 minutes long

The entire show including the introduction, will last 130 minutes

Thus the remaining time for performances is:

Performance time = 130 minutes - 25 minutes

Performance time = 105 minutes

To find, the number of performances, divide the 105 by 7 minutes

$Number\ of\ performances = \frac{105}{7} = 15$

Thus 15 performances can be accommodated
