Question

2. Suppose Bernard is the only supplier of both coffee and donuts in Smalltown. The cost of producing the goods is zero. Bernard sells coffee for $3 and donuts for $3. In a typical hour, 5 costumers buy just one coffee, 4 buy just one donut, and 3 costumers buy one of each. The owner finds that those who buy only coffee would also buy a donut if the donut were $2. And those who buy only a donut would also buy coffee if the coffee were $1. If he is considering offering a coffee +donut bundle, so that consumers could buy either just coffee, just donuts, or both of them bundled together, what price for the bundle will maximize his profits

Explanation / Answer

At the current price of $3 for both coffee and donuts, currently the profits are 5 x 3 + 4 x 3 + 3 x (1 x 3 + 1 x 3) = 45

There are three choices for bundled price: $4, $5, and $6.

Optimum bunlde price is $5 and the separate prices are $3 for each donut and coffee. This is because at this pricing, those who buy dounts at $3 and are likely to buy the bundle, find that it is beyond their willingness and so they buy only donuts. Profit from them is $3*4 = $12. Profit from other consumer types = (5 + 3)* 5 = $40. Total profit = $52.
