Answer: a. 0.042 b. 0.086 c. 0.00692
Explanation:
NOTE: Convert months to years. So 24 months = 2 years.
a. Six months
Months to year conversion gives: 6months/24months as 1/4 years
= (1 + 18%)^ 1/4 — 1 x 100%
= 1.042 — 1
= 0.042
Equivalent Discount Rate = 0.042
b. One year
12months/24months as 1/2 years
= (1 + 18%)^1/2 — 1 x 100%
= 0.086
Equivalent Discount Rate = 0.086
c. 1 month
1month/24months as 1/24 years
= (1 + 18%)^1/24 — 1 x 100%
= 0.00692
