Use the formula for continuous compounding to compute the balance in the account after 1, 5, and 20 years. Also, find the APY for the account. A $2000 deposit in an account with an APR of 3%. The balance in the account after 1 year is approximately [...]
Future value for continuous compunding = Present value * e^( r*t )
e = 2.7183
r = interest rate = 3%
t = time = 1 year
Future value = 2000 * 2.7183^( 0.03*1 ) = 2061
t = time = 5 years
Future value = 2000 * 2.7183^( 0.03*5 ) = 2323.67
t = time = 20 years
Future value = 2000 * 2.7183^( 0.03*20 ) = 3644.24
Annual percentage yeild for continuos compounding = e^r - 1
e = 2.7183
r = interest rate = 3%
APY = 2.7183^0.03 - 1 = 3.04%
Balance in the account after 1 year = 2061 (as calculated above)
