Boxes of fruit snacks are on sale at the grocery. The boxes are the same size. A family needs to purchase 24 boxes. There are 3 boxes for 5 dollars and 4 boxes for 6 dollars. Which snacks should they purchase if they want to spend lesser amount? How much will they save?

Answer 1

The family should purchase the 4 boxes for 6 dollars to spend a lesser amount of money. They will save $4.

Answer 2

Explanation:

To solve the given question we will find the price of 24 boxes using different rates of the boxes.

"If the rate is 3 boxes for 5 dollars."

∵ 3 boxes costs = $5

∴ 1 box costs =
`(5)/(3)`

∴ 24 boxes costs =
`(5* 24)/(3)`

= $40.00

"If the rate is 4 boxes for 6 dollars"

∵ 4 boxes costs = $6.00

∴ 1 box will cost =
`(6)/(4)`

∴ 24 boxes will cost =
`(6* 24)/(4)`

= 6 × 6

= $36

Therefore, snacks of 4 boxes for $6 will be economical and amount saved 40 - 36 = $4.00
