Question

31) Joe spent half of his weekly allowance

playing mini-golf. To earn more money
his parents let him clean the windows in
the house for $4. What is his weekly
allowance if he ended with $11?

Answer 1

$26

Explanation:

11 times 2 = $22 plus the extra he make cleaning windows is $26

The reason I did 11 times 2 is because he spends halve of his money on golf so to find what he had before he spent it on golf I had to do it times 2

Answer 2

To help solve this problem, create a simple equation.

Let x = weekly allowance.

(x/2) + $4 = $11. Subtract 4 from each side

(x/2) = 7. Multiply each side by 2

x = $14.

Joe's weekly allowance is $14
