A bakery sells cupcakes for $2 each and offers a discount of $0.50 for every 12 cupcakes purchased. If a customer buys n cupcakes, write a function D(n) for the total cost after discounts. What is the domain of D(n)?

D(n) = 2n - 0.50 * (n // 10), domain: n >= 0

D(n) = 2n - 0.50 * (n // 12), domain: n >= 0

D(n) = 2n - 0.50 * (n / 12), domain: n >= 1

D(n) = 2n + 0.50 * (n // 12), domain: n > 0
