SOLVED PROBLEMS
3.1 Find (a) the ordinary and (b) the exact simple interest, on a 60-day loan of $1500
at 14%
We have P = 1500 and r = .0145.​

Answer 1

Exact = $34.5

Ordinary = $35

Step-by-step explanation:

Given that :

Principal, P = $1500

Interest rate = 14% = 0.14

Number of days = 60

For exact :

Exact simple interest uses 365 days :

Simple interest = principal * rate * time

Simple interest = $1500 * 0.14 * 60 / 365 = 34.520547 = $34.5

For ordinary simple interest :

Simple interest = principal * rate * time

Simple interest = $1500 * 0.14 * 60 / 360 = $35
