Question

You wash dishes for a chemistry laboratory to make extra money for laundry. You earn 12 dollars/ hour, and each shift lasts 75 minutes. Your laundry requires 12 quarters/load.

How many loads of laundry will each shift pay for if the cost per load rises to 16 quarters?
Please do explain in simple terms and equations. I suck at math, thank you!

Answer 1

I could only do 3 loads of laundry.

$12.00/hr x 75 Minutes (1.25hrs) = $15.00

1 load of laundry costs $4.00

1 shift = $15.00 Earned / $4.00 per load = 3.75 loads of laundry
