Question

Azarel spent half of his weekly allowance on comic books. To earn more

money his parents let him clean the windows in the house for $9. What is
hsi weekly allowance if he ended up with $12? *

Answer 1

His weekly allowance is $6.

Explanation:

You can get the answer by using algebraic expressions.

Let 2x be Azarel's weekly allowance.

Let
`(1)/(2)`(2x) be the amount after Azarel spends his allowance on comic books.

The equation will be: 12=2x+9-
`(1)/(2)`(2x)

Let's solve for x:

Step 1: 12=2x+9-x

Step 2: 12=x-9

Step 3: x=12-9

Step 4: x=3

Step 5: Replace 2x with 2(3) = 6

The answer is $6. This is the allowance of Azarel every week. He spends $3 for comic books weekly, which is half of $6.
