Question

Volunteers at Sam's school use some of the student council's savings for a special project. They buy 8 backpacks for $4 each and fill each backpack with paper and pens that cost $3. By how much did the student council's savings change because of this project?

Answer 1

Student council's savings reduced by
`\$56`

Explanation:

Given:

Volunteers buy 8 backpacks for $4 each and fill each backpack with paper and pens that cost $3

To find:

Change in student council's savings

Solution:

Cost of paper and pens in each backpack =
`\$3`

Total cost of paper and pens in 8 backpacks =
`\$8`×
`\$3` =
`\$24`

Cost of each backpack =
`\$4`

Total cost of 8 backpacks =
`8`×
`\$4` =
`\$32`

So, student council's savings reduced by
`\$32+\$24=\$56`
