Question

Hello, I need help implementing a program in f# for an example problem: "Suppose that the tuition for a university is $10,000 this year and increases 5% every year. In one year, the tuition will be $10,500. Write a program that displays the tuition in 10 years and the total cost of 4 years’ worth of tuition starting after the 10th year." I don't have a lot of experience with functional programming languages. Can someone show me how to go about doing this? It's hard to think about things functionally when I'm so used to thinking about things imperatively. Thank you in advance.

open System
[<EntryPoint>]
let main (args : string[]) =
      
        printfn "Enter the tution fee";
        let tutionfee = Console.ReadLine();
        
        printfn "Enter fee increase rate";
        let rate = Console.ReadLine();

//Loop to find total tution fee after 10 years

for i = 1 to 10 do
    let futureValue1    = tutionfee * ((1.00 + i) ** rate);
    let interestEarned1 = futureValue1 - tutionfee;
let totalamount1 = futureValue1;

//Loop to find total tution fee after 10 years

for i = 1 to 4 do
    let futureValue2    = tutionfee * ((1.00 + i) ** rate);
    let interestEarned2 = futureValue2 - tutionfee;
let totalamount2 = futureValue2;

printfn "The Tution fee after 10 years is %f" totalamount1;
printfn "The Tution fee after 2 years is %f" totalamount2;
