Question

Justin spent 45% of his paycheck on travel expenses. If he earned $800, how much money did he spend, and how much money is left over?

Answer 1

1. He spent $360

2. Amount left over = $440

Explanation:

Let us first layout the important details in the question:

Amount earned = $800

percentage spent on travel expenses = 45% of the amount earned

45% of the amount earned

`= (45)/(100) * 800\\= 0.45 * 800 = 360`

∴ Amount sent on travel = $360

To find the amount of money left over, we will simply deduct the amount spent from the total earned amount. This is done as follows:

Amount left over = Amount earned - Amount spent on travel

Amount left over = 800 - 360 = $440

∴ $440 was left over
