A cookie recipe requires for 3/4 flour and 1/3 cups of butter to make one batch of cookies. Wendy has 2 cups of flour and 3/4 cups of butter. What is the greatest number of batches she can make?

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
