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?

do explain in simple terms and equations. i suck at math, you!

 3.75 per shift

Step-by-step explanation:

Given : The amount earned by laundry = 12 dollars / hour

Since 1 dollar = 4 quarters.

Then, amount earned per hour= quarters per hour.

    [By unitary method]

The time period for each shift = 75 minutes

Since 1 hour = 60 minutes

Then , 1 minute = hours     [By unitary method]

Now, 75 minutes = hours

Now, the total amount earned from each shift will be:-

quarters

Now , the cost of laundry= 12 quarters/load

The cost of load after increment = 16 quarters

Then, the number of loads can be washed :-

Hence, number of loads of laundry = 3.75 per shift
