Answer:
A) 18 boxes
Step-by-step 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 [tex]\frac{7.38}{18}=\$0.41[/tex]
27 $15.39 [tex]\frac{15.39}{27}=\$0.57 [/tex]
30 $13.50 [tex]\frac{13.50}{30}=\$0.45[/tex]
36 $18.36 [tex]\frac{18.36}{36}=\$0.51[/tex]
40 $18.80 [tex]\frac{18.30}{40}=\$0.46[/tex]
On comparing the unit prices of each we find out that cost of 18 boxes is the cheapest and hence the best deal.
