Making Purchases
Shopping is an integral part of our day-to-day lives. From the food in your fridge, to the clothes in your closet, most of the items in your home were purchased from somewhere: maybe from a store, an online shop, or an individual. How we decide on what to buy depends on a number of factors. One of the most influential factors is money. Whether you are shopping in Canada or in a foreign country, you need to know how much money you have and how much an item costs in order to make an informed decision about your purchase. In this section, you will learn how to choose the best price by comparing unit prices and considering price increases and decreases. You will also learn how to make wise shopping choices when traveling in other countries by learning how to convert between different currencies.

In this section, you will:
• investigate how unit prices, price increases and decreases, as well as currency exchange, influence purchasing decisions
