Question

Jessica spent half of her allowance going to the movies. She washed the family
car and earned 9 dollars. What is her weekly allowance if she ended with
17 dollars ?

Answer 1

Answer:

16 dollars.

Step-by-step explanation:

She ended with 17 dollars after earning 9 dollars, so her amount of money before earning this was 17 - 9 = 8 dollars.  This is half of her weekly allowance, so her weekly allowance is double this or 16 dollars.
