If I understand u, suppose that value is the money, and period is the time payed for that amount of money, and 1$ = 1 hour (60 minutes) of time, then the function could be:

function GetPeriod(Value: Double): Integer;
begin
  Result:= Round(Value * 60);
end;

example

  edPeriod.Text:= IntToStr(GetPeriod(StrToFloat(edValue.Text)));

I forget to mention that the result is minutes, for example

if you enter 1 you will get 60 minutes
2 = 120 minutes, and so on
