Raul deposited $3000 into a bank account that earned simple interest each year. After 3.5 years, he had earned $262.50 in interest. If no money was deposited into or withdrawn from the account, what was the annual interest rate? Enter your answer in the box.
Answer:
assuming simple interest
I=PRT
I=262.5
P=3000
R=?
T=3.5
262.5=3000(?)(3.5)
262.5=10500?
divide both sides by 10500
0.025=?
2.5%=?
answer is 2.5%
