Question

I have figured out 3 out of 5 cases on this task, but since there are 2 cases that aren't answered correctly, there is a problem with my code. I will be posting the question here and my attempt in the comments section.

Answer 2

This is the attempt i used to solve three cases, and still don't know what is wrong with my code.

#include <iostream>
using namespace std;

int main() {

int BrushesAndCanvas = 40.00;
int paints;

cin >> paints;

int PaintsPrice = paints* 5.00;
float tax = 0.1;
int total = (PaintsPrice + BrushesAndCanvas );

double total2 = total * tax;

int total3 = total + total2;

cout << total3 ;

return 0;
}

Answer 3

Hakam, you did show your attempt, but is this a code-coach pro code?

Answer 4

Dino Wun (Use the search bar plz!) no, it's on the free version.

Ri He won't making the output "int" would round the answer to the nearest whole number?
