Question

Janice sold several items in a garage sale. She spent one-half of the money she made on a new bicycle. Next she spent one-half of what was left on a portable stereo set. If Janice had $80.00 left, how much money did she make from the garage sale?

Answer 1

The total money Janice earned from the garage sale was $320.

How to calculate Janice's earnings?

To calculate Janice's profit from the garage sale we must perform the following mathematical operations.

Based on the money she had left at the end we can calculate how much her total earnings were. To do this we multiply $80 by 2 to calculate half of her earnings as shown below:

• $80 × 2 = $160

Based on the above, we know that Janice had $160 after buying her bike that cost half of her total earnings. Therefore, to know the amount of her earnings we must multiply $160 by 2 as shown below:

• $160 × 2 = $320

Based on the above, it can be inferred that Janice's total earnings were $320.
