Jeff spent half of his weekly allowance playing mini golf. To earn more money his parents let him wash the car for $4. What is his weekly allowance if he ended with $12?

Answer:the weekly allowance of Jeff is $16

Step-by-step explanation:

Let x represent the weekly allowance of Jeff.

Jeff spent half of his weekly allowance playing mini golf. This means that the amount that Jeff spent playing golf would be

x/2. He has x/2 left.

To earn more money his parents let him wash the car for $4. This means that the total amount of money that he has left would be

x/2 + 4

If he ended up with $12, it means that

x/2 + 4 = 12

x/2 = 12 - 4 = 8

x = 8 * 2 = 16

Simple form answer $12 - $4 = $8 add 8+8 because he used half of his weekly pay at mini golf $8 + $8 = $16

Therefore Jeff's weekly allowance is $16
