When someone lends money to someone else, the borrower usually pays a fee to the lender. This fee is called 'interest'. 'Simple' interest, or 'flat rate' interest. The amount of simple interest paid each year is a fixed percentage of the amount borrowed or lent at the start. <span>Interest = Principal × Rate × Time</span>
If you are using a calculator, simply enter 16÷72×100 which will give you 22.22 as the answer.
17/2 = 8.5 hours per week
8.5 x 5 = 42.5 hours in 5 weeks
R=i/pt
R=16/200*2=0.04*100=4%
