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?
