Question

Kelli and Karl each have a job. Kelli earns $20 an hour. She also receives a $100 weekly bonus.

Kelli made a table to show how much she earns in a given week.

Hours 0 5 10 15 20 25 30 35 40
Weekly Earnings 100 200 300 400 500 600 700 800 900
Karl earns $25 an hour and receives a $50 weekly bonus.

Karl made a graph to show how much he earns per hour in a given week.



How many hours will it take Kelli and Karl to earn the same amount of money?

Answer 1

25h + 50 = 20h + 100

25h - 20h + 50 = 100

5h + 50 = 100

5h = 100 - 50

5h = 50

h = 50/5

h = 10

How I built my equation:

How much Kelli makes a week * h (number of hours she works) + 100 (weekly bonus) = How much Karl makes a week * h (number of hours he works) + 50 (weekly bonus).

It's been a while since I've done this but I'll double check my answer right now.
