Answer:
A school wanted to see how many students bought orange juice with their lunch. As a result, they sampled 100 lunch-buying students, to see how many of them bought orange juice. In a sample of 100 lunch-buying students, 25 of them bought orange juice with their lunches. If there are 1,000 students in the school that buy lunch, how many students bought orange juice with their food? 250.
Step-by-step explanation:
I'm assuming there's no visual included in the question, and that the example can be completely original.
If you wanted a ratio, you would ask what the ratio was between students that bought lunch and students that bought orange juice with their lunches (often asked in lowest terms).
- Sample included 100:25
- You want it in lowest terms. Find the lowest common denominator
- LCD = 5
- New ratio, divided by five to find lowest terms
- = 20:5
- Every 20 students, 5 of them (also 25% of them) bought orange juice with their lunches.
It would be 4 and 5 since those are two angles whose measures have a sum of 180.

Answer:
Total sales = $3600
Commission earned on $3600 = $576
Commission rate can be calculated as =
= 16%
Hence, the commission rate is 16%
