Buff is considering a new packaging machine. The initial cost is $10,000 and we would save $4,000 per year in labor costs. If our MARR is 12% and our projects must have a 3-year discounted payback period, should we purchase this packaging machine? Yes
No
Not enough nformation to answer.

NO

Explanation:

Discounted payback calculates the amount of time it takes to recover the amount invested in a project from it cumulative discounted cash flows

For the machine to be accepted, the total amount invested should be recovered in three years or less

Amount recovered = - cost of the project + discounted value of the cash flow

Amount recovered in year 1 = -10,000 + (4000 / 1.12) = -6,428.57

Amount recovered in year 2= -6,428.57 - (4000/ 1.12^2) = -3239.74

Amount recovered in year 3=  -3239.74 + (4000/ 1.12^3) = -392.62

the project would not be accepted because the amount invested would not be recovered within 3 years
