Answer:
b. 4 years
Step-by-step explanation:
The cash payback period calculates how long it takes for the amount invested in a project to be recovered from the cumulative net cash flows.
The total amount invested = - $490,000
In year 1, $180,000 is recovered. The amount remaining of the money invested is - $490,000 + $180,000 = $-310,000
In year 2, $120,000 is recovered. The amount remaining of the money invested is $-310,000 + , $120,000 = $-190,000
In year 3, $100,000 is recovered 100,000. The amount remaining of the money invested is $-190,000 + 100,000 = $-90,000
In year 4, $90,000 is recovered. The amount remaining of the money invested is $-90,000 + $90,000 = 0
The amount invested is recovered in 4 years. This is the cash payback period.
