Question

You can work a total of no more than 41 hours each week at your two jobs . House cleaning pays $5 per hour and your sales job pays $8 per hour . You need to earn at least $254 each week to pay your bills. Write a system of inequalities that shows the various numbers of hours you can work at each job

Answer 1

Let's introduce variables first:

H - hours of house cleaning

S - hours of sales

Now read the problem from the beginning making equations ( in this case - inequalities)

work a total of no more than 41 hours each week at your two jobs:

H + S <= 41

You need to earn at least $254:

H*5 + S*8 >= 254
