Question 3 4 points Save Answer A gourmet cook bakes three types of cakes (chocolate, vanilla, and strawberry) to supplement her income. Each chocolate cake requires 20 minutes of baking time, uses 4 eggs, and can be sold for 40 TL. Each vanilla cake requires 30 minutes of baking time, uses 2 eggs, and can be sold for 30 TL whereas each strawberry cake requires 25 minutes of baking time, uses 3 eggs, and can be sold for 35 TL. The cook has 12 hours of baking time and 60 eggs. Based on the previous sales, the cook expects that she can sell up to 40 cakes every day and she does not want to bake more than that. She also observed that the demand for chocolate cakes is higher; thus, she does not want to bake more than 1 vanilla cake for every 2 chocolate cakes and no more than 2 strawberry cakes for every 3 chocolate cakes. She wants to maximize her income. Which one of the below constraints is not required in developing a mathematical model for this system? a. the number of vanilla cakes in proportion to the number of chocolate cakes O b. the number of strawberry cakes in proportion to the number of chocolate cakes O c. baking time constraint O d. usage of egg constraint O e. demand constraint for each cake type
