uppose you're sitting in a local pizza shop, eating slices of pizza one at a time. Your decision: how many slices to purchase? Assume the price of each slice is $1.50. Note that this unit price is the marginal cost of each unit for the consumer. That is, each slice costs you an additional $1.50. Also assume we can measure your marginal (additional) benefit from each slice in dollars as follows: Slice Marginal Benefit 1 $4.50 2 2.75 3 1.51 4 0.75
