Hard to say, it is wrong. According to wiki, the US had 127 golds prior to the start of these Olympics and we have currently won 2 more, so our total (including Phelps) should be 129. Not sure the best way to separate those out, since 8 of his golds were on relays.

I think you drastically underestimate how fast a fire can move in an airplane cabin, making even seeing the blinking floor lights nearly impossible. Is a laptop/passport worth someone dying for?

Your values don’t line up quite right: $3750+$5100=$8850, so I’m assuming your total is correct and you didn’t list the vehicle value correctly and it should be $3775
