6. A small company plans to spend $10,000 in year 2 and $10,000 in year 5. At an interest rate of effective 10% per year, compounded semiannually, the equation that represents the equivalent annual worth A in years 1 through 5 is: (a) A 10,000( PIF,10%,2) ( AIP,10%,5) + 10,000 ( A_IF,10%,5) (b) A= 10,000(AIP,10%,4)+ 10,000(A_F,10%,5) (c) A=10,000( PIF,5%,2)( AI P,5%,10)+10,000( A_IF,5%,10) (d) A=10,000( FIP,10%,5)+ 10,000] ( AIF,10%,5) 7. Assume you make monthly deposits of $200 starting one month from now into an account that pays 6% per year, compounded semiannually. If you want to know the total after 4 years, the value of n you should use in the FIA factor is: 8.
