Is the Bigger Bag Really Cheaper?

Two bags of oats, a breakfast food, cost$ 2 and$ 3.60. Which is cheaper? You need to know how much food is inside, not just the price.
The$ 2 bag holds 500 grams. The$ 3.60 bag holds 1,000 grams. For every 100 grams, the small bag costs 40 cents and the large bag costs 36 cents. The large bag is cheaper for the same amount, but you pay more at the shop.
Some shops show the price for 100 grams. If not, divide the price by the number of grams, then multiply by 100. This helps when bag sizes make the choice difficult.
Always compare prices for the same amount. A price for one kilogram is not the same as a price for 100 grams. Compare similar foods, too.
Also, think about how much you will use. A 200-gram bag of salad costs$ 2. A 400-gram bag costs$ 3. If you eat only half the large bag before it goes bad, you pay$ 3 for food you could buy for$ 2.
Do you have enough space and money for a bigger bag? Read any rules for special offers, too.
The best choice gives you what you need at a fair price, without buying too much.
