Having trouble with easy kaleidoscope challenge

Question

I'm trying to practice and get better at programming by doing the challenges i need assistance with one of them I feel like I'm close to solving it but can't figure it out

Kale is price of kaleidoscope, buy is how many is being bought, tax is the 7% tax, and no_dis is no discount if user buy 4 they get a 10% discount

def purchase(kale, buy, tax):
no_dis = kale * buy + tax
if buy == 4:
no_dis / 10
return no_dis

x = 5
y = int(input())
t = x * 0.07
tax = t + x
result = purchase(x, y, tax)
print(result)

Marshall Lance Freeman ,

here some hints you may follow:

the current code is quite difficult to read and understand, because calculation and logic is split up in main program and a function.

● the basic task is to check if a discount can be given or not.●

> if the number_of_items purchased is greater than 1:
give discount
> else
give NO discount

try to simplify also the calculation itself.

if discount can be given (eg 3 items are purchased):
number_of_items * price_per_item * discount * tax
>>> 3 * 5 * 0.9 * 1.07

if discount can not be given (eg 1 item is purchased):
number_of_items * price_per_item * tax
...

the final output should be rounded to 2 decimal places
