Molly spent half of her weekly allowance on candyTo earn more money her parents let her wash the dog for $8. What is her weekly allowance is she ended with $16?

Question

How much was her weekly allowance ?

Answer 1

Here's what we know:

16 = ½ x + 8 (half of her allowance plus the 8 from dog washing is $16)

We start by subtracting 8 from both sides:

16 - 8 = ½ x + 8 - 8

8 = ½ x

Now we multiply both sides by 2:

8 * 2 = ½ x * 2

16 = x

So her weekly allowance is $16.
