Question

A certain brand of coffee comes in two sizes. An 11.3-ounce package costs $3.68. A 29.3-ounce package costs $8.98. Find the unit price for each size. Then state which size is the better buy based on the unit price. Round your answers to the nearest cent.what is the answer?

Answer 1

To find the unit price for each size divide the cost of each package by the corresponding weight.

Size 1

`(3.68)/(11.3)=0.32`

The unit price is $0.32/ounce

Size 2

`(8.98)/(29.3)=0.31`

The unit price is $0.31/ounce

Size 2 is better to buy because it has a cheaper unit size, it means you can buy more ounces with the same amount of money if you buy size 2.
