3) (10 points) There is a collection of small-scale irrigated wheat farming operations in the area over multiple acres and farms. From talking with producers, you have an estimate for aggregate marginal costs for fertilizer over the aggregate acreage. This leads you to a supply curve for fertilizer. These costs and quantities are listed below. Cost of Fertilizer/Price Aggregate Quantity of Acres $10 5 $20 15 $30 27 $40 35 $50 40 $60 46 $70 50 a. Graph private marginal costs (aggregate) for fertilizer over the acreage specified, b. Shade in the marginal private costs of moving from fertilizing roughly 30 acres to fertilizing 40 acres C. There is a large rain event that washes the fertilizer into a nearby river. This causes an algal bloom. Draw and label on the same graph a marginal social cost curve reflecting this event. Indicate on the graph where the marginal social costs are from fertilizing roughly 30 acres to fertilizing 40 acres. Be sure that this area is clearly defined
