Question: Brenda invested $300 into a scheme that accumulates simple interest at the rate of three-quarters of the original amount per year. How much in total will she have after 3 years?
Can you solve this problem?
Answer: 
Three-quarters of $300 is (3/4)*$300 = $225
After 3 years, interest of $225*3 = $675 has been accumulated
She now has a total of $300+$675 = $975
