Question

It will take 4 people a total of 63 hours to build a deck. How many people are needed to build the same type of deck in 36 hours?

Answer 1

Well the equation for the given information 63/4 = How long it takes everyone to build the deck
63/4 = 15.75
15.75
567 

Answer 2

Well,

63 divided by 4 equals 15.75

So, each person holds 15.75 hours.

15.75 * 2 people = 31.5 hours, so that would not work.

15.75 * 3 people = 47.25, which is the closest you're going to get.

Correct answer: 3 people
