A builder wants to build the cross section of a bridge shown in the diagram. 55 ft 4 in. Beam 3 ft IHI Description of Diagram Specs: • The cross section is 55 ft 4 in. wide. • The distance between each end of the bridge to the first I-beam is 3 ft. • The thickness of each web of the l-beam is ft. • The distance between each I-beam is b. 1. An equation to find the distance b between each beam is 2. The approximate distance b between each consecutive pair of l-beams is Two companies offer simple bids on building the bridge cross-section above according to the distance b and the number of l-beams. EMPIRE DESIGN BUILD-EM-UP CO. Bid Form Bid Form Proposal: $300,000 - b S60,000 per l-beam Proposal: $320,000 -b 540,000 per l-beam 3. a. What is the current total bid from each company for building the cross section? b. Which company would you choose if you want to accept the least expensive bid? 4. If the cross section could be redesigned for cost reasons in terms of b, what is the distance b where both companies would have the same bid on the project?
