Abharsa spent half of her weekly allowance at the movies. To earn more money her parents let her clean the windows for 7$. What is her weekly allowance if she ended with 12$

Respuesta :

Answer: $10

Step-by-step explanation:

If weekly allowance is x

Half of it is x/2

Remaining half plus $7 is $12

x/2 + 7 = 12

Subtract by 7 both sides

x/2+7-7 = 12 - 7

x/2 = 5

Multiply both sides by 2

(x/2)*2 = 5*2

x = 10
