, where P is the principal amount ,r is the rate of interest ( in decimal) and t is the time period ( in years).

Given : Dante borrows $500 from his older sister and agrees to pay her 6% simple annual interest.

i.e. P=$500     ;   r=6%=0.06

Now, the simple interest Dante will owe at the end of 3 years will be :-

Hence, Dante will owe $90 as interest at the end of 3 years.
