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

int main() {
int canvas_brush,color,total,tax;

scanf("%d",&color);

canvas_brush=40;
tax=(canvas_brush+(color*5))*0.10;
total=ceil(canvas_brush+(color*5)+tax);

printf("%d",total);
return 0;
}

Answer 1

Try changing the variables from int to float. It is likely the tax calculation is losing important fractional value.

Answer 2

^That was the case. Thanks!
