Due to the budget sequester, the bridge department had their repair budget reduced for the coming year. The cost of repair for several bridges needing repair are shown below.

Also shown is the average number of cars per day that travel over each bridge. If the bridge department only has sufficient resources to repair one bridge per year, which one should be repaired first from a cost effectiveness perspective?

Bridge Repair Costs Average Cars per day
Washington $2,400,000 1600
Adams $2,700,000 1500
Jefferson $2,300,000 1740
Madison $2,240,000 1550
Jackson $2,000,000 1440
