part a: describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value. (5 points)
part b: how many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? show your work. (5 points)

PART A)

divide the total cost by the number of bushels

 24/3 = 8,

 so a bushel of corn cost $8

PART B)

previous year corn cost 21/3 = $7 a bushel,

 so this year it costs $1 more a bushel

so what is the question

step-by-step explanation:

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
