<human>:  A wooden bridge can carry no more than 5000 pounds. A delivery truck filled with identical boxes, each weighing 15 pounds, will pass over the bridge. The combined weight of the driver and the empty truck is 3755 pounds. What is the maximum number of boxes which can be loaded onto the truck while not exceeding the bridge's weight limit?
<bot>: How much can the boxes weigh? ** The boxes can weigh up to 5000 pounds - 3755 pounds = <<5000-3755=1245>>1245 pounds in total.
How many boxes can be loaded onto the truck? ** There can be 1245 / 15 = <<1245/15=83>>83 boxes loaded onto the truck without exceeding the bridge's weight limit.
