Salt Mixture B is defined by the equation y = 2.5x, where x is the number of teaspoons of salt and y is the number of cups of water. If you used 10 cups of water, which mixture would use more salt?

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
