Final answer:
Coca-Cola Enterprises (CCE) purchases four vending machines for a total cost of $360, with each machine costing $120. The vending machines have a useful life of 3 years.
Step-by-step explanation:
CCE purchases three vending machines for $120 each, costing a total of $360. KO pays for a fourth machine, also costing $120. Therefore, CCE will own a total of four vending machines by paying $360 out of pocket.
The useful life of each vending machine is 3 years, meaning they are expected to be operational for that period of time.
