A travel agency charges $64 for each bus ticket and $82 for each train ticket. How much does it cost to buy 3 bus tickets and 3 train tickets?
The cost of 3 bus tickets is 3 x $64 = $<<3*64=192>>192.
The cost of 3 train tickets is 3 x $82 = $<<3*82=246>>246.
Buying 3 bus tickets and 3 train tickets would cost $192 + $246 = $<<192+246=438>>438. Answer: \boxed{438}.
