Question

Abhasra spend half of her weekly allowance at the movies to earn more money her parents let her clean the windows in the house for seven dollars what is her weekly allowance if she ended with $12

Answer 1

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
