A construction worker is placing rivets in a new bridge. He uses 42 rivets to build the first 2 feet of the
bridge. If the bridge is to be 2200 feet in length, predict the number of rivets that will be needed for the entire bridge.

about 105 rivets to build 2200 ft of the bridge .

Step-by-step explanation:

104.76 rounded is 105
