Simple interest

Question

On June 3rd 2014 Helen borrowed $1600 from a bank. The bank charged 14% simple interest, Helen paid her note off on sept 4th 2014, how much interest did she have to pay ? 

Answer 1

Interest = Principle*Rate*Time

 

Where:

Principle = the amount of money borrowed = $1600

Rate = the annual interest rate expressed as a decimal = 14% = 0.14

Time = years = 3 months = 0.25 years

 

Interest = ($1600)*(0.14)*(0.25)
