Suppose a monopoly produces commercial cameras and film. Pictures require film and one camera. Two different types of consumers have the following demand forfilm:

QA= 100p

and

QB= 120p.

The monopoly cannot price discriminate in the market for film or the market forcameras, but it can bundle the products. The monopoly produces film at a constant marginal cost of$20 per cartridge. What price will the monopoly set for film and forcameras?
