If it takes 15 people 8 hours to make 100 items how many hours will it take 6 people working at the same rate to make half as many items?

To solve this problem you must calculate the rate per person.
15 people take 8 hours to make 100 items
15p * 8h = 100i
120ph = 100i
1.2ph = i.
So each item takes 1.2 person hours to complete (or 72 person minutes)
If we need to make 50 items we need 1.2 * 50 person hours (or 72* 50 person minutes)
We need 60 person hours.
Since we have six people, each person needs to work 10 hours.
