Adams County's Board of Representatives is considering the construction of a longer runway at the county airport. Currently, the airport can handle only private aircraft and small commuter jets. A new, long runway would enable the airport to handle the midsize Jets used on many domestic flights. Data pertinent to the board's decision appear below. Cost of acquiring additional land for $ 84,000 runway Cost of runway construction 285,000 Cost of extending perimeter fence 17,792 Cost of runway lights 46,000 Annual cost of maintaining new runway 23,000 Annual incremental revenue from 60,000 landing fees In addition to the preceding data, two other facts are relevant to the decision. First, a longer runway will require a new snowplow, which will cost $185,000. The old snowplow could be sold now for $18,500. The new, larger plow will cost $17,000 more in annual operating costs. Second, the County Board of Representatives believes that the proposed long runway, and the major jet service it will bring to the county, will increase economic activity in the community. The board projects that the increased economic activity will result in $104,000 per year in additional tax revenue for the county. In analyzing the runway proposal, the board has decided to use a 10-year time horizon. The county's hurdle rate for capital projects is 19 percent. Use Appendix A for your reference. (Use appropriate factor(s) from the tables provided.) Required: 1. Compute the initial cost of the investment in the long runway. Initial cost of investment 2. Compute the annual net cost or benefit from the runway. Annual net benefit Annual net cost 3-a. Determine the IRR on the proposed long runway.

The county's hurdle rate for capital projects is 19 percent. The County Board of Representatives believes that if the county conducts a promotional effort costing $28,500 per year, the proposed long runway will result in substantially greater economic development than was projected originally. However, the board is uncertain about the actual increase in county tax revenue that will result. Required: Suppose the board builds the long runway and conducts the promotional campaign. What would the increase in the county's annual tax revenue need to be in order for the proposed runway's internal rate of return to equal the county's hurdle rate of 19 percent? (Round Intermediate and final answer to the nearest dollar amount.) Required increano in tax revenue
