Answer 1

We can find the unit price of each size by dividing their cost by the amount of coffee each size contains.

• For the 12.3 ounce, we get:

`(2.99)/(12.3)=0.24`

The unit price for the 12.3 ounce is $0.24 per ounce

• For the 33.9 ounce:

`(8.74)/(33.9)=0.26`

The unit price for the 33.9 ounce is $0.26 per ounce

Then, the 12.3-ounce size is the best buy, since its unit price is the lowest.
