14

$24

Which package offers the best deal?

3 for $8

5 for $8

12 for $24

14 for $24

Answer:

5 for $8

Explanation:

Given:

3 batteries sell for $8

5 batteries sell for $8

12 batteries sell for $24

14 batteries sell for $24

To find the package that offers the best deal, find the cost of each battery by dividing each total cost by the number of the batteries. The package with the lowest will be the best package.

Thus:

Package 1:
`(8)/(3) = 2.67`

Package 2:
`(8)/(5) = 1.60`

Package 3:
`(24)/(12) = 2.00`

Package 1:
`(24)/(14) = 1.71`

The best package here is package 2 where 5 batteries sell for $8, because the cost of each battery here is significantly lower than the cost of each battery in other packages.
