Courtney has a cookie-baking business, and is baking 250 cookies to sell at a weekend festival. The cookies will be sold for $1.50 each. Courtney's total weekend profit can be represented by the function P(c) = 1.50c, where c is the number of cookies sold. What is the domain of P(c)?

• all non-negative multiples of 1.50

• all non-negative number including zero

• all non-negative integers less than or equal to 250

• all non-negative integers and zero
