The simple interest formula is A = P(1 + r)^t  where P represents the amount originally deposited, r is the interest rate, and A is the amount in the account after t years.

Find r if A = 2[c]00, P = 2[a]00 and t = 5.  (Note: if [c] = 7, then 2[c]00 = 2700)

Express r as a percentage to one decimal place (x.x%).
