Paddy's Confidential has 600 cans of stew required to feed 40 people. How many cans would be needed to feed 30% fewer people?
Thoughts? Step-by-step reasoning:
If there are 40 people, each person gets 600 / 40 = 15 cans. Thirty percent of the total number of people present is 30 / 100 * 40 = 12. If there are 30% fewer people, the number of people who are to be fed is 40 - 12 = 28. Since each person is given 15 cans, twenty - eight people will need 15 * 28 = 420 cans.
Thus, the answer is 420.
