Question

Stephanie spent half of her weekly allowance playing arcade games. To earn more money her parents let her clean the oven for $7. What is her weekly allowance if she ended with $12?

15 dollars
5 dollars
8 dollars
19 dollars

Answer 1

Stephanie's weekly allowance is $10.

Step-by-step explanation:

To find Stephanie's weekly allowance, we need to determine how much she spent playing arcade games and how much she earned by cleaning the oven. Let's say Stephanie's weekly allowance is x dollars. According to the question, she spent half of her allowance playing arcade games, which is (1/2)x dollars. She also earned $7 by cleaning the oven. We can set up the following equation: (1/2)x + 7 = $12. To solve for x, we need to isolate it by subtracting 7 from both sides of the equation: (1/2)x = $12 - 7 = $5. To get rid of the fraction, we can multiply both sides of the equation by 2: x = 2 * $5 = $10.
