As a salesman, Audrey earns $75 per week plus $5 per sale. This week, she wants her pay to be at least $125. Write and solve an inequality for the number of sales Audrey needs to make.

he needs to make at least 10 sales.

Step-by-step explanation:

Let x represent the number of sales that the salesman makes in a week.

As a salesman, Audrey earns $75 per week plus $5 per sale. This means that if he makes x sales in a week, his total earnings would be

5x + 75

This week, she wants her pay to be at least $125. Therefore, an inequality for the number of sales Audrey needs to make is

5x + 75 ≥ 125

5x ≥ 125 - 75

5x ≥ 50

x ≥ 50/5

x ≥ 10

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
