Each shift worked can pay for 3.75 loads of laundry if each load costs 16 quarters.
<h3>Further Explanation</h3>
This problem can be solved using simple dimensional analysis. The steps are:
- Sort the given. Identify the conversion factors or equalities that may be used. Identify what is required.
- Set up the dimensional analysis ensuring that units cancel out until only the desired unit is left. The equalities in the problem may be used as conversion factors.
STEP 1: Sort first the given in the problem to identify possible conversion factors to be used in the dimensional analysis.
The following equalities are given in the problem:
- 1 shift = 75 minutes
- 12 dollars = 1 hour
- 1 load = 16 quarters
- 1 dollar = 4 quarters
STEP 2: From these equalities, the following dimensional analysis can be set up:


Therefore, one shift can pay for 3.75 loads of laundry.
