You deposit $400 into an account that pays 2% annual interest compounded quarterly.
part a: write an exponential model that describes the situation.
part b: determine the value of the account after 5 years. round to two decimal places.

Part A

Write an exponential model that describes the situation.

Y (x)=400 (1+0.02/4)^4x

Y the value of the account after x years

400 is the initial deposite

0.02 interest rate

4 compounding periods (quarterly)

X time ( number of years )

Y (x)=400 (1.005)^4x

Part B

Y (5)=400×(1.005)^(4×5)=441.96
