# The Long Wait

## INTRODUCTION

It’s difficult to save money when you’re working part-time.

Your friend Andre works part-time as a painter and he is saving his money so he can buy your favourite video game. How long will you have to wait until you can play it with him?

## THE PROCESS

1. What is the video game you most want to play? Go to Amazon.ca to see a selection of games. What platform does it operate on?

2. Andre doesn’t have the equipment to play the game. He has to buy all the equipment first, including the platform.

3. Andre works 25 hours each week to make \$225 dollars. Andre doesn’t want to use all the money he makes to buy games. He saves 30% of his earnings every week for college tuition. He spends another 50% on clothes, movie tickets, music, and so on. He spends \$30 each week getting to work and on food and drinks while he’s working.

4. How long will it be before you and Andre can play the game, if you wait for him to buy it? Show your work, and explain how you decided on your answer.
