Question

Susan is a college student with two part-time jobs. She earns $10 per hour tutoring elementary students in math. She earns $15 per hour cleaning in the library. Her goal is to earn at least $240 per week, but because of college, she does not work more than 20 hours each week.

Part A

Let e represent the number of hours Susan works in one week tutoring elementary students, and let c represent the number of hours Susan works in one week cleaning the library.

Which Inequalities represent Susan's goal for earning money and the number of hours she can work in one week?

Select all that apply.

A. c + e ≤ 20

B. 15c + 10e ≤ 20

C. 15c + 10e ≥ 20

D. c + e ≤ 240

E. 15c + 10e ≤ 240

F. 15c + 10e ≥ 240

Answer 1

10 per hour tutoring
e = hours tutoring
so 10e
15 cleaning
c = hours cleaning
so 15c
15c + 10e and she wants to make at least 240
So option E is one answer

Answer 2

And since she does not want to work more than 20 hours
≤ 20
and the hours are c and e
so c + e ≤ 20
Option A

Answer 3

so it's just those 2 ?

Answer 4

Yes
