#include <stdio.h> #include <math.h> int main() { int colors; scanf("%d", &colors); printf("%d", (int)round(1.1 * (5 * colors + 40))); return 0; }

Why there are 2 int main functions, also the cost must be rounded off to a nearest whole number.

Expected output: "[...] rounded up to the nearest whole number."

I think that's just an copy & paste error with those 2 mains and imports/includes.

Sandra Meyer may be that can be copy paste error, but that will surely cause an error

#include <math.h> And then (int) round(value)

You have to round the result BEFORE you assign a temporary result to an integer variable, otherwise you've already produced information loss before you rounded.

Try all these steps in one command, one line: tax = 0.10 * (color+brush); cost= brush + color +tax; x = round(cost); OR (alternatively), use float for all the steps before you're rounding the result (but did not try this option).

BRYAND CHE Use ceil function from math library Use #include <math.h> to include math library. Then x=ceil(cost)

BRYAND CHE Try this code ..... #include <stdio.h> #include <math.h> int main() { int color, brush,tax,cost; scanf("%d", &color); brush = 40 ; color*=5; tax =ceil( 0.10 * (color+brush)); cost= brush + color +tax; printf("%d", cost); return 0; }
