Answer:
a) 39.304%
b) 67.91%
c) 14.17%
Explanation:
a. Given"
Offer terms = 1.8/10
Now,
The Effective annual interest rate is given as:
= [tex](\frac{\textup{100}}{\textup{100 - Discount rate}})^{(\frac{365}{total period - discount period})}-1[/tex]
on substituting the respective values, we get
= [tex](\frac{\textup{100}}{\textup{100 - 1.8}})^{\frac{365}{(30 - 10)}}-1[/tex]
= 0.39304
or
= 39.304%
similarly,
b. for 2.8/10 net 30
Effective annual interest rate = [tex](\frac{\textup{100}}{\textup{100 - 2.8}})^{(\frac{365}{(30 - 10)})}-1[/tex]
= 0.6791
or
= 67.91%
c. for 1.8/10 net 60
Effective annual interest rate = [tex](\frac{\textup{100}}{\textup{100 - 1.8}})^{(\frac{365}{(60 - 10)})}-1[/tex]
= 0.1417
or
= 14.17%
