Question

Find the amount of money in an account after 9 years if $2100 is deposited at 8% annual interest compounded quarterly. 

Answer 1

2100(1 + 0.08/4)⁴⁽⁹⁾

 

Throw that in your calculator for your answer.

Answer 2

Principal P=2100

 

interest rate r=8%, compounded quarterly is 8/4 = 2%

100%+2% = 102% = 1.02

 

Quarterly for 9 years, the interest shall accumulate 9x4=36 times

 

2100*(1.02)^36 = 4283.76
