Which is the better buy? A 12 pack of Pepsi for \$3.50 or a 6 pack for \$1.80?

The 12 pack.

1.80×2=3.60

6 pack of pepsi is \$1.80

12 divided by 6 is 2.

1.80 x 2 is 3.60

If you buy two of the 6 pack pepsis, it would have 12 pack of pepsi but would cost \$3.60. If you buy the 12 pack, it would be \$3.50 so it would be the 12 packs being the better deal.

*note* I'm stupid so I would probably buy the 6 packs twice ;(

From the graph of the constraints, the corner points of the feasibility region are (0, 0), (0, 10/3), (1, 3), (2, 0)

For (0, 0): p = 0 + 2(0) = 0
For (0, 10/3): p = 0 + 2(10/3) = 20/3 = 6.67
For (1, 3): p = 1 + 2(3) = 1 + 6 = 7
For (2, 0): p = 2 + 2(0) = 2

For all the corner points, the maximum is at point (1, 3)

Therefore, solution = (1, 3)
