Answer:
the discount payback period is 1.49 year
Step-by-step explanation:
The computation of the discount payback period is as follows;
= 1 year + ($5,500 - $4,078.80) ÷ ($2,897.64)
= 1 year + ($1,421.20) ÷ ($2,897.64)
= 1 year + 0.49 years
= 1.49 year
Hence, the discount payback period is 1.49 year
