Question

Volunteers at sam's school use some of the student council's savings for a special project. They buy 7 backpacks for $8 each and fill each backpack with paper and pens that cost $5. By how much did the students councils savings change because of this project?

Answer 1

They buy 7 backpacks for $8 each and fill each backpack with paper and pens that cost $5

Cost of 1 backpack = $8

cost of 7 backpacks = 8 * 7 = $56

Cost to fill each backpack with paper and pens = $5

Cost to fill each 7 backpacks with paper and pens = 5 * 7=$35

Total cost = $56 + $35 = $91

the students councils savings change by $91

Answer 2

7 times 8= 56
7 times 5=35
Now you add 56+35, which equals, 91 dollars.

The student council's savings changed, or decreased, by 91 dollars.
