# function : future value # input : three numbers (PV (float), r (float), and n (int ) ) ; # determines the future value of a dollar processing : amount given the PV, r, and n. # output : The future value calculation Here's the sample program that you will use to test your function. Copy the definitions.: following lines and paste them into your python program file under your method answerl = future_value (100, 0. 05, 5) print (answerl) answer2 = future_value (20000, 0.05, 10) print (answer2) answer3 = future_value (4000, 0. 03, 1) print (answer3) answer4 = future_value (900, 0. 06, 4) print (answer4) And here's the expected output: 127.63 32577.89 4120.00 1136.23
