Answer:
Calculation of annual interest with a simple interest rate for Rachel :
Annual interest (Rachel) = Initial amount × interest rate
Annual interest (Rachel) = 60000 × 0.02
Annual interest (Rachel) = $1200
Rachel will receive annual interest of $1200 for the first three years.
Calculating annual interest with a compound interest rate for Michael :
For interest compounded annually, the formula for calculating interest is :
Annual interest (Michael) = Initial amount × (1 + interest rate)^number of years - initial amount
Annual interest (Michael) = 60000 × (1 + 0.02)^1 - 60000
Annual interest (Michael) = 60000 × 1.02 - 60000
Annual interest (Michael) = 61200 - 60000
Annual interest (Michael) = $1200
Michael will also receive annual interest of $1200 for the first three years, even with compound interest.
Rachel and Michael will receive $1200 annual interest for the first three years.
