2. A lunch stand makes s.75 profit on each chef's salad and $1.20 profit on each Caesar salad. On a typical weekday, it sells be

kow [346]

Let's let

x = the number of chef salads, x>=0

y = the number of Caesar salads, y>=0

The constrains are:

40 <= x <= 60

35 <= y <= 50

x + y <= 100

The objective function here is F(x, y) = 0.75x + 1.20y

The corner points are (40, 35), (60, 35), (60, 40), (50, 50) and (40, 50).

F (40, 35) = 0.75*40 + 1.20*35 = $72

F (60, 35) = 0.70*60 + 1.20*35 = $84

F (60, 40) = 0.75*60 + 1.20*40 = $93

F (50, 50) = 0.75*50 + 1.20*50 = $97.50

F (40, 50) = 0.75*40 + 1.20*50 = $90

Thus, we conclude to maximize the profit 50 Chef and 50 Caesar salads should be prepared.

Answer:

301.44 cubic units

Step-by-step explanation:

$volume \: of \: cone \\ \\ = \frac{1}{3}\pi {r}^{2} h \\ \\ = \frac{1}{3} \times 3.14 \times {(6)}^{2} \times 8 \\ \\ = \frac{1}{3} \times 3.14 \times 36 \times 8 \\ \\ = 3.14 \times 12 \times 8 \\ \\ = 301.44 \: {units}^{3} \\ \\ \red{ \bold{volume \: of \: cone = 301.44 \: {units}^{3}}}$
