Question

stephanie spent half of her weekly allowance playing arcade games. To earn more money her parents let her clean the oven for $7. what is her weekly allowance if she ended with $12?

Answer 1

$10.00

Explanation:

Let Stephanie's weekly allowance = x

She spent half of her weekly allowance playing arcade games =
`(x)/(2)`

Her parents let her clean the oven for =
`(x)/(2)+7`.

She ended with $12

So the equation will be
`(x)/(2)+7=12`

`(x)/(2)` = 12 - 7

`(x)/(2)` = 5

x = 5 × 2

x = 10 dollars

Her weekly allowance would be $10.00
