Two designs for a facility to be built have been identified as follows: Design A Design B Cost of site: Cost of structure: Annual fee collection: Annual maintenance cost: Service Life: $300,000 $2,800,000 $890,000 $460,000 30 years 250,000 $1,900,000 $650,000 $360,000 30 years At the end of the structure's service life, the structure would have no salvage value. If the city of Cheney's interest rate is known to be 8%, which design would be selected using the benefit-cost ratio
