Divisora de Cuentas y Calculo de Propinas

For this solution I did not want to focus on perfection in the design, however I tried to make it as close as possible, I focused on the main functionality which was to calculate the total and divide the bill, taking the tip as part of it.

I translated some words into Spanish, since that made it easier to show it to my friends.

Here in Venezuela when you collect money for something or pay a bill together it is called "Vaca" let's make "a Cow for this..."

Feel free to evaluate my solution, any suggestion is welcome.
