economi analysis of nutua Design: 101 a bridge design firm is performing highway overpass. The steel girder option has an initial cost of $2.29 million, and the concrete option has an initial cost of $2.57 million. Every 25 years, the steel bridge must be painted at a cost of $610,000, and all other maintenance costs are the same for both options. The steel bridge is expected to last 50 years, and concrete bridge is expected to last 75 years. Both are assumed to be identically replaced indefinitely. Based on the shortest acceptable analysis period for each option, determine the equivalent uniform annual cost (EUAC) for the best option using an interest rate of 9%. Express your answer in $ to the nearest $1,000.

Question

A bridge design firm is performing an economic analysis of two mutually exclusive designs for a
highway overpass. The steel girder option has an initial cost of $2.29 million, and the concrete
option has an initial cost of $2.57 million. Every 25 years, the steel bridge must be painted at a
cost of $610,000, and all other maintenance costs are the same for both options. The steel bridge
is expected to last 50 years, and concrete bridge is expected to last 75 years. Both are assumed to
be identically replaced indefinitely. Based on the shortest acceptable analysis period for each
option, determine the equivalent uniform annual cost (EUAC) for the best option using an interest
rate of 9%. Express your answer in $ to the nearest $1,000.

Littrell's Nursery needs a new irrigation system. System one will cost $145,000, have annual maintenance costs of $10,000, and need an overhaul at the end of year six costing $30,000. System two will have first year maintenance costs of $5,000 with increases of $500 each year thereafter. System two would not require an overhaul. Both systems will have no salvage value after 12 years. If Littrell's cost of capital is 4%, using annual worth analysis determine the maximum Littrell's should be willing to pay for system two.
