Each candy bar will be sold for $2, what is the minimum number of candy bars that must be sold to meet the goal of raising at least $1000

Question

The goal is to have 150 students in the school to sell candy bars for the fundraiser. On average, how many candy bars must be sold per student to meet the goal?

Answer 1

To raise $1000, 1000/2=500 bars must be sold by 150 students (between them). 500/150=10/3=3⅓. If each student sold 3 bars, then this would raise 3×150×2=$900, insufficient to meet the goal. But if each student sold 4 bars they would raise $1200. If 3 students sold 10 bars between them as a group, 50 groups would raise $1000. On average, the number of bars is 3⅓ for each student.
