The minimum is the first number listed as it is the lowest, and the maximum … The solution provided is as follows: P(x) = xp(x) - c(x) = x(-5x + 39) - 4(x +30) =-5x^2 + 39x -4x - 30 = 5x^2 + 35x - 30 = -5(x^2 - 7x + 6) = -5(x-1)(x-6) The zeros of the profit function are at x = 1 and x = 6. At that point, they'll want you to differentiate to find the maximums and minimums; at this point, you'll find the vertex, since the vertex will be the maximum or minimum of the related graphed parabola.But they're the same exercise and you'll get the same answers then as you will now. I can get you started. You need to order between 20 and 26 pounds of meat and in each case calculate the expected profit and from this determine which size order has the largest expected profit.
