Suppose that Lion and Tiger stop advertising but must determine the price they will charge for each pizza sold. Lion believes that Tiger’s price can be $6 (with 25% chance), $8 (with 50% chance) or $10 (with 25% chance). If Lion charges a price x, and Tiger charges a price y, Lion will sell 100 +25(y-x) pizzas. It costs Lion $4 to make a pizza. Lion is considering charging $5, $6, $7, $8, or $9 for a pizza.
a) Construct Lion’s profit decision matrix depending on own possible prices, respectively Tiger’s possible prices.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
