Answer:
$10.00
Step-by-step explanation:
Let Stephanie's weekly allowance = x
She spent half of her weekly allowance playing arcade games = [tex]\frac{x}{2}[/tex]
Her parents let her clean the oven for = [tex]\frac{x}{2}+7[/tex].
She ended with $12
So the equation will be [tex]\frac{x}{2}+7=12[/tex]
[tex]\frac{x}{2}[/tex] = 12 - 7
[tex]\frac{x}{2}[/tex] = 5
x = 5 × 2
x = 10 dollars
Her weekly allowance would be $10.00
