[iteration for array map()] I Got Bills (6-9)]

/*
 * Programming Quiz: I Got Bills (6-9)
 *
 * Use the .map() method to take the bills array below and create a second array
 * of numbers called totals. The totals array should contains each amount from the
 * bills array but with a 15% tip added. Log the totals array to the console.
 *
 * For example, the first two entries in the totals array would be:
 *
 * [57.76, 21.99, ... ]
 *
 * Things to note:
 *  - each entry in the totals array must be a number
 *  - each number must have an accuracy of two decimal points
 */
 
 /*
 * QUIZ REQUIREMENTS
 * - Your code should have the variables `bills` and `totals`
 * - Your `bills` array should call the `map()` method and store the return of `map()` in the `totals` array
 * - Your `totals` array should be an array of numbers
 * - Your code should print the `totals` array to the console
 * - The output must be as described above.

    return Number(element); //with map you have return the result, make sure the array is numbers
});
