The market for an agricultural product is modelled by the following Demand and Supply Curves: Demand: Q d = 800 – 30P Supply:

Qs = 20P – 100

Where Q is quantity measured in tons, and P is the Price $ per ton

The government decides to provide producers with a subsidy of $4 per ton.

The competitive model predicts that, as a result of the subsidy, the equilibrium market price will fall by? (Include working out)
