Who can figure this out ??

Question

IN PYTHON:
Build an algorithm that calculates your savings at retirement..

-invest an unknown amount at the end of every year
-earn an unknown intrest rate on their savings
-DOUBLE their annual investment every second year

Answer 1

Sorry but i think that it must work differently... Follow my try:

- year 1
investiment: 100
earn: 50% = 50
total savings: 150

- year 2
investiment: 200
earn: 50% = 100
total savings= 150 + 300= 450

- year 3
investiment: 200
earn: 50% = 100
total savings: 450 + 300= 750

- year 4
investiment: 400
earn: 50% = 200
total savings: 750 + 600= 1350

Answer 2

Why you dont post your try? In this way we can help but dont think that someome make YOUR assignement for you

P.S. Please, dont spam other discussion

Answer 3

def oh(PV,i,n):

    FV=PV
    for j in range(n):
        if j % 2 == 0:
            interest = (FV*2) *i

            FV = FV + interest
            print(FV)
        else:
            interest = FV * i
            FV = FV + interest

    return FV

Answer 4

Mario Moshogiannis Ok... I dont understand one thing... Why you calculate interest every year? You cannot do it to end?

Answer 5

Mario Moshogiannis Just for understand what you have to find, you can tell me what your algorithm would return for:

- after 1 year, with 10 as initial amount and 0% interest

- after 1 year, with 10 as initial amount and 5% interest

- after 2 year, with 10 as initial amount and 0% interest

- after 2 year, with 10 as initial amount and 5% interest

Answer 6

let me try this

year 1 =100 +50% so end of year 1 =150

year 2 the man deposits 200 .. so 350.. +50% = 525..

year 3 man deposited 200 again..
so 725 +50% = 1087.50

year 4... man deposits 400... so 1487.50 +50% = 2231.25

this is what i could understand from the question

im just struggling to get it to work as an algorithm

Answer 7

yours is making more sence.. but do i keep the same structure with running a loop ans an if statement in my loop?

Answer 8

its a savings account so interest builds yearly

Answer 9

you can keep same structure but remember than

range(n)

retunr (0,1,2...n)

then the first year is 0 and because 0%2 equals to 0 you get doubled your investiments every 2 years but starting from first year (and its not that do you want i think)... Futhermore if you apply interest to only saving year, you can calculate final saving applying interest at last (without calculate it every year). Following my previous example:

totalSavingsWithoutInt= 100+200+200+400= 900

totalSavings= 900 * (interest + 1)= 900 * 1.5= 1350
