Use matrix multiplication to determine the cost, in dollars, under the two purchase options (small and large quantities) to fill the day’s order.

The Original Cookie Factory bakes and sells four types of cookies: chocolate chip, sugar, molasses, and peanut butter. Matrix A indicates the number of units of various ingredients used in baking a dozen of each type of cookie.

The cost, in cents per cup or per egg, for each ingredient when purchased in small quantities and in large quantities is indicated in matrix B below.

Suppose a typical day’s order consists of 40 dozen chocolate chip cookies, 30 dozen sugar cookies, 12 dozen molasses cookies, and 20 dozen peanut butter cookies.
