Answer 2

Coder Kitten

#include <stdio.h>
#include <math.h>

int main() {
int colours, total, other_stuff=40, a;
double tax, final;
scanf("%d",&colours);

total = (colours*5) + other_stuff ;

tax = total/10.0;

final = tax + total;

a = ceil(final);

printf ("%d",a);

return 0;
}

This is the new code and it works thank you
