Find the future value of the following annuities. The first payment in these annuities is made at the end of Year 1, so • they are ordinary annuities. (Notes: If you are using a financial calculator, you can enter the known values and then press the appropriate key to find the unknown variable. Then, without clearing the TVM register, you can "override" the variable that changes by simply entering a new value for it and then pressing the key for the unknown variable to obtain the second answer. This procedure can be used in many situations, to see how changes in input variables affect the output variable. Also, note that you can leave values in the TVM register, switch to Begin Mode, press FV, and find
the FV of the annuity due.) Do not round intermediate calculations. Round your answers to the nearest cent.
a. $400 per year for 10 years at 14%.
b. $200 per year for 5 years at 7%.
