Sasha spent half of her allowance going to the movies. She washed the family car and earned $6. What is her weekly allowance if she ended with $15?

Answer 1

Her weekly allowance is $18

Explanation:

We can use an algebraic equation to solve this problem.

x/2 + 6 = 15

x/2 + 6 ( - 6) = 15 ( - 6)

x/2 ( · 2)= 9 ( · 2)

x = 18

Her weekly allowance is $18
