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.
In a year with 12 months, the total number of vehicles passing through the old bridge is 2000*12 =

<output>24_000</output>
24000.
The new bridge has a capacity of 60/100*2000 = 
<gadget id="calculator">60/100*2000</gadget>
<output>1_200</output>
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 = 
<gadget id="calculator">2000+1200</gadget>
<output>3_200</output>
3200.
There are 3200*12 = 
<gadget id="calculator">3200*12</gadget>
<output>38_400</output>
38400 vehicles passing through the new bridge in a year.
Altogether, the two bridges have 38400+24000 = 
<gadget id="calculator">38400+24000</gadget>
<output>62_400</output>
62400 vehicles passing through them in a year.
