Question

During the day Sam spent $4.85 on lunch. He also bought.Two book for $7.95 each at the end of the day he had $8.20 left how much money did he start with

Answer 1

He started with $28.95

Explanation:

You add all the money he spent and how much he had left because this equals how much money he had all together before he bought anything.

x = 4.85 + 7.95 (2) + 8.20

x = 4.85 + 15.90 + 8.20

x = 28.95

Answer 2

$28.95

Explanation:

Sam started out with x dollars.

We represent this situation with the following formula:

x - ($4.85 + $7.95 + $7.95) = $8.20.

Then:

x - $20.75 = $8.20.

To isolate x, we add $20.75 to both sides of this equation, obtaining:

x = $28.95.

Sam started out with $28.95.
