Answer:

Her weekly allowance is $10

Step-by-step explanation:

Let's call x her weekly allowance

At the end she has $12. She obtained this for the addition of the money she earned cleaning windows ($7) and the half of her weekly allowance (the other half she spend it at the movies). Mathematically:

x/2 + 7 = 12

Solving for x:

x/2 = 12 - 7

x = 2*5

x = $10
