Answer:
$28.95
Step-by-step 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.
Answer:
He started with $28.95
Step-by-step 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
