Example 1: Your good friend needs a loan to start his latest enterprise and has 
requested that you lend him $450 for 60 days. You lend him the money at 7% 
simple interest, to be calculated on a 360-day basis. What is the amount of 
accrued interest he will owe you in 60 days, and what is the total amount owed?

450Þ$

Example 2: Your friend agrees to the 7% interest on the loan from the preceding 
example, but asks that you compute it on a 365-day basis rather than a 360-day 
basis. What is the amount of accrued interest he will owe you in 60 days, and 
what is the total amount owed?
