You wash dishes for a chemistry laboratory to make extra money for laundry. You earn 12 dollars/hour, and each shifts lasts 75 minutes. Your laundry requires 12 quarters/load. How many loads of laundry can you wash if you work 3 shifts? How many loads of laundry will each shift pay for if the cost per load rises to 16 quarters?

Explanation:

The following information is provided :

Amount earned per hour = 12 dollars/hour

Duration for one shift = 75 minutes = 1.25 hours

Cost per load = 12 quarters/load

A. Cost of 10 loads of laundry = 12 × 10 = 120 quarters

120 quarters = 120/4 dollars = 30 dollars

Time taken to earn 30 dollars = 30/12 × 1 hour = 2.5 hours

Number of shifts required in 2.5 hours = 2.5/1.25 = 2 shifts

Therefore, 2 shifts are required to wash 10 loads of laundry

B. Duration of 3 shifts = 1.25 hours × 3 shifts = 3.75 hours

Amount earned in 3 shifts = 3.75 × 12 = 45 dollars

12 quarters/load = 12 × 0.25 dollars = 3 dollars/load

Number of loads that can be washed = 45/3 = 15 loads of laundry

Therefore, 15 loads of laundry can be washed in 3 shifts

C. 16 quarters/load = 16 × 0.25 = 4 dollars/ load

Amount earned per shift = 1.25 × 12 =15 dollars

Loads of laundry per shift = 15/4 = 3.75 loads

Therefore, 3.75 loads will be paid per shift
