Answer:
her weekly allowance is $10
Explanation:
Let x represent Abhasra's weekly allowance.
Abhasra spent half of her weekly allowance at the movies. This means that the total amount that she spent on the movies is x/2. The amount that she is left with would be
x - x/2 = x/2
In order to earn more money, her parents let her clean the windows in the house for seven dollars. This means that the total amount left with her is
x/2 + 7
if she ended with $12, it means that
x/2 + 7 = 12
x/2 = 12 - 7 = 5
x = 2 × 5 = $10
