conversations.value: Find the answer to the math problem: The country of Belize had a 5 lane bridge that had 2000 vehicles passing through it every month. They decided to build a new bridge that had twice the capacity of the old one, and the number of vehicles passing through the new one increased by 60% more than the old bridge. If the bridges work concurrently for a year, calculate the total number of vehicles that pass through the two bridges.

conversations.value: In a year with 12 months, the total number of vehicles passing through the old bridge is 2000*12 = 24000
  The new bridge has a capacity of 60/100*2000 = 1200 more vehicles passing through it in a month than the old one.
  The total number of vehicles passing through the new bridge in a month is 2000+1200 = 3200
  There are 3200*12 = 38400 vehicles passing through the new bridge in a year.
  Altogether, the two bridges have 38400+24000 = 62400 vehicles passing through them in a year.
