Answer 1

//You have to round the result as in description mentioned:
#include<stdio.h>
#include<math.h>
int main()
{
float paints;
scanf("%f",&paints);
float cost=round((paints*5+40)*11/10);
printf("%.f",cost);
}

Thanks a lot for ur suggestion JaScript 😊..

Answer 3

the code seems to be fine. you may typecast tax:
tax = (int)(num/10);
sometimes the "/" operator may cause trouble to integers. just an idea but it might not make any difference anyway.
