In answer to Jim Gajniak:
It seems to me that the model should be y = M(1 - e^(-kx)) where x
represents the area of the Pizza and Y represents the price. I think a
fairly good graph is: y = 24(1 - e^(-.0023x)) (I placed the data points
into the equation and solved by using the ISECT command on the TI-85) (the
law of diminishing returns will dictate that after awhile the pizza will
get too large to place in an oven, (with apologies to Sadam, and the
"mother of all pizzas", of course) So, therefore, the answer to the
question of which is better is: neither is better than the other. The
both obey the model. I wonder if any pizza stores actually do any
mathematics when they price their pizzas?
