Q:

A) 18 boxes
B) 27 boxes
C) 30 boxes
D) 36 boxes

Answer 1

A) 18 boxes

Explanation:

The table given shows the number of boxes of paperclips and their costs.

Number of boxes Cost

18 $7.38

27 $15.39

30 $13.50

36 $18.36

40 $18.80

To find the best value we will find the unit cost per box by dividing the total cost of boxes by number of boxes.

Number of boxes Cost Unit cost

18 $7.38
`(7.38)/(18)=\$0.41`

27 $15.39
`(15.39)/(27)=\$0.57`

30 $13.50
`(13.50)/(30)=\$0.45`

36 $18.36
`(18.36)/(36)=\$0.51`

40 $18.80
`(18.30)/(40)=\$0.46`

On comparing the unit prices of each we find out that cost of 18 boxes is the cheapest and hence the best deal.
