Question

A 12 ounce can of Coke costs $1.00 when purchased from the soda machine at the school. An 16 oz bottle of Pepsi from the soda machine at the local gas station costs 1.35. Is the can of coke or bottle of Pepsi the best buy?

Answer 1

Answer:

Can of Coke

Step-by-step explanation:

Calculate how much money each ounce of drink costs, or the money per ounce ($/oz).

Coke:

$/oz = $1 ÷ 12oz = $0.083333/oz

Pepsi:

$/oz = $1.35 ÷ 16oz = $0.084375/oz

Coke < Pepsi

0.083333 < 0.084375

The calculations show that you would pay more money for one ounce of Pepsi than for one ounce of Coke. Coke costs less than Pepsi.

Therefore the can of Coke is the best buy.
