Chelsea spent half of her weekly allowance playing arcade games. To earn
more money her parents let her clean the
windows in the house for $10. What is
her weekly allowance if she ended with
$18?

I believe it would be 16

Step-by-step explanation:

8 is half of 16 and if she had 8 dollars after spending half her allowance, she would've had 16 as her allowance

Final Her allowance would be 16 dollars
