Cost of a single Mars Exploration Rover, delivered to Mars, in 2008
dollars: $480,000,000

Predicted cost of the NASA Reference Mars Mission (manned), in 2008
dollars: $66,000,000,000

66E9/480E6 = 137.5

In common usage, 137.5 is not "hundreds", nor is 1.45 "a fraction".

Math. It's not just for breakfast any more.
