Coach Code ( Paint Cost).

Question

I don't know why test 3 and 4 are failing in my code. Here it is :

n = int(input())
cost =40.0
canvas = n*5
tax = int((cost+canvas)*0.1)
total = round(cost + canvas + tax)
print(total)

Answer 1

Marvellous Abia
Why you use int when calculating tax

Answer 2

The instructions ask you to ROUND UP to the nearest whole number.
Try ceil()

Answer 3

Mihai Apostol thanks

Answer 4

Mihai Apostol I can't believe that's what's been holding it. Thanks. It worked.

Answer 5

Please use search bar. Many had problems with this Code Coach Challenge.
Do some research.

Answer 6

Marvellous Abia
from math import ceil

or

import math

and then to call it

math.ceil()

Answer 7

Marvellous Abia You're welcome.

And belive that, because when using int you were removing the decimal part of that result.

Answer 8

well this is what i use and i guarantee you that it works perfectly
def cost(color):
brush = 40
paint = color*5
tax = (brush+paint)*0.1
if (tax%5!=0):
tax+=0.5
total = int(brush+paint+tax)
return(total)
n = cost(int(input()))
print (n)

Answer 9

ceil() is not a default function. I think it has to be defined first.

Answer 10

from math import ceil

n = int(input()) I just
cost =40.0
canvas = n*5
tax = int((cost+canvas)*0.1)
total = ceil(cost + canvas + tax)
print(total)

Is still giving the same issue. test 1,2, and 5 passed but 3 and 4 didn't. Those 2 guys didn't read, I guess that's why they failed.

Answer 11

do this it clears all the test cases, your solution dont not work cuz its not rounding up the number properly.

def cost(color):
brush = 40
paint = color*5
tax = (brush+paint)*0.1
if (tax%5!=0):
tax+=0.5
total = int(brush+paint+tax)
return(total)
n = cost(int(input()))
print (n)

Answer 12

to use ceil function import math and use ceil function as math.ceil

import math

def cost(color):
brush = 40
paint = color*5
tax = math.ceil((brush+paint)*0.1)
total = brush+paint+tax
return(total)
n = cost(int(input()))
print(n)
