1. (6 pts.) Dogwood City is taking bids from six bus companies (A, B, C, D, E, F) on eight routes that must be driven each day in their school district. Each company submits its bids (in $) for how much it will charge Dogwood City to drive the routes during the school year. However, only company F actually bids on all eight routes, as seen in the table below. Blank cells indicate that a company is not bidding on a particular route.
