Question

Cottage cheese is being sold in different size containers. The sizes and prices are given below:
4 - 5 ounce containers for $5.00
1 - 12 ounce container for $3.24
1 - 16 ounce container for $4.19
Which container is the better buy?
a.
The 5 ounce container is the better buy.
b.
The 12 ounce container is the better buy.
c.
The 16ounce container is the better buy.
d.
The containers have the same unit price.

Answer 1

Compute price per ounce for each:

- 4 × 5 oz = 20 oz for $5.00 → $5.00 / 20 = $0.25/oz
- 12 oz for $3.24 → $3.24 / 12 = $0.27/oz
- 16 oz for $4.19 → $4.19 / 16 ≈ $0.2619/oz

The lowest unit price is $0.25/oz, so (a) the 5-ounce containers (the 4-pack) are the better buy.
