Joshua invested $750 in an account paying an interest rate of 3 1/4% compounded quarterly. Josiah invested $750 in an account paying an interest rate of 2 5/8 % compounded annually. After 18 years, how much more money would Joshua have in his account than Josiah, to the nearest dollar?
Due to the difference in the interest rate and the quarterly compounding, Joshua will have $212.24 more than Josiah. Step-by-step explanation: Giving the following information: Joshua: Initial investment (PV)= $750 Interest rate (i)= 0.0341/4= 0.008525 Number of periods (n)= 18*4= 72 quarters Josiah: Initial investment (PV)= $750 Interest rate (i)= 0.0285 Number of periods (n)= 18 years To calculate the future value of each one, we need to use the following formula: FV= PV*(1 + i)^n Joshua: FV= 750*(1.008525^72) FV= $1,381.98 Josiah: FV= 750*(1.0285^18) FV= $1,169.74 Due to the difference in the interest rate and the quarterly compounding, Joshua will have $212.24 more than Josiah.
