If a bank account begins the year with a $50 balance, but ends the year with $55, what is the implied annual interest rate?
If interest rates are currently 5% per year, then what is the interest earned on a $200 investment in one year? (Don't enter the dollar sign
The interest rate is computed as shown below:
Future value = Present value x (1 + r)n
$ 55 = $ 50 x (1 + r)1
$ 55 / $ 50 = 1 + r
1.1 - 1 = r
r = 10%
The interest amount is computed as shown below:
= Amount of investment x interest rate
= $ 200 x 5%
= $ 10
