Answer:
$14
Explanation:
After Shanice spent half of her allowance and earned $7, she is left with $14.
This means the remaining of her weekly allowance is $7, This can be derived by subtracting $7 from 15 - $14 - $7 = $7
This means that it is $7 that remains after spending half of her weekly allowance
her weekly allowance = $7 x 2 = $14
