Question 1165947

20000(1+0.06)^10=$35,816.95

the other way is x=20000/(1.06^10)=$11,167.90

the third is 20000*(1.015)^40=$36,280.37. divide inside interest by 4 and multiply outside exponent by 4 since this is 4 times a year

next one is x* (1+(0.06/4))^40=20000; 
x=$11,025.25. You don't need to invest as much since more compounding times is more interest


the fifth  is x*(1+.06/12)^120 =20000, and this will be $10,992.65

going the other way, one will have 20000*(1+(.06/12))^120, or $36,387.93
