Marginal anylasis is thinking at the margin or when right before you will make the choice
A.
producing another car
depends on how fast you can product, I don't think it is very fast, so no
B.
this is marginal thinking, you already have the pizza in front of you
c. same as A, not
D. you are already buying one
B and D
(x - 8)^2 = 144
take the sq rt of both sides
x - 8 = 12
x = 12 + 8
x = 20
20 feet by 20 feet
4x + 100 > 7x
100 > 3x i moved all the x's over to one side
100/3 > x
or just
x > 100/3
so they need to sell more than 33.33333... pizzas
No one makes a 1.3333... pizza as far as I know, so your answer might be 34.
It is 0.25 since you divide 3 by 25 since you can't simplify the it any more
