Answer:
His weekly allowance is $6.
Step-by-step explanation:
You can get the answer by using algebraic expressions.
Let 2x be Azarel's weekly allowance.
Let [tex]\frac{1}{2}[/tex](2x) be the amount after Azarel spends his allowance on comic books.
The equation will be: 12=2x+9-[tex]\frac{1}{2}[/tex](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.
