Shuttle: launch cost $600M, payload 24 tons max (+7 astronauts) = $25M
per ton to ISS

Falcon/Dragon: COTS+CRS funds to SpaceX $2.1 Bn / 20 tons (and ZERO
astronauts) = $105M per ton to the ISS

so, the "cheap" Falcon/Dragon price-per-ton-to-ISS is OVER FOUR TIMES
HIGHER than the "expensive" Shuttle!!!

also, send seven astronauts with a Soyuz (instead of a Shuttle) will
cost $51M per seat x 7 = $357M

You calculations are wrong.

The CRS cargo weight is what is deliver to the ISS. The cargo is in
the form of bags. That is how Spacex gets paid, not cargo to orbit
which would include the weight of the Dragon.

To be an apples to apple comparison. The shuttle payload capability
(24 tons ) is not the correct number to use. It is the carrying
capability of an MPLM, which is around 5 tons.

So shuttle cost is 120 million per ton
