Two roadway designs are under consideration for access to a permanent suspension bridge. Design 1A will cost $1.8 million to build and $125,000 per year to maintain. Design 18 will cost $3.6 million to build and $40,000 per year to maintain. Both designs are assumed to be permanent. Use an AW-based rate of return equation to determine (a) the breakeven ROR and (b) which design is preferred at an MARR of 35% per year a) The breakeven ROR is 96. b) At an MARR of 35% per year, desigr Y (Click to select) is preferred 1B 1A
