Answer:
2.3 years
Step-by-step explanation:
The payback period is the amount of time required for cash inflows generated by a project to offset its initial cash outflow. The averaging method and subtraction method are two ways used to calculate the payback period.
Since, we are to use the averaging method, which is to divide the annualized expected cash inflows into the expected initial expenditure for the asset.
First, we determine the average inflows:
average inflow = (sum of amount of cash inflows for each year )/number of years
average inflow = ($8000+$6000+$5000+$6000+$5000)/5
average inflow = $6000
Payback Period = Initial investment/ Avg Inflows
Payback Period = $14,000/$6,000 = 2.3 years
Using the averaging method, the payback period for the investment in the oven would be 2.3 years
