how much exactly is it? a factor of 100
0 context: the article is talking about how to reduce the cost of transport by rocket. 02 br
00 it states that "it currently costs approximately $10,000 per pound to put payloads in orbit, more than their value if they were made of gold." 02 br
02 br
00 later it says: 02 br
02 br
00 "Efforts are underway to bring down rocket costs through the use of reusable launch vehicles, but costs will have to come down by a factor of at least 100 in order to develop a mass market." 02 br
02 br
00 now I understand the phrase "by a factor of" means "a degree of", but I have trouble in understanding the following number 100. 02 br
02 br
00 what does it mean: 100 of what? dollars? pounds? percent? 02 br
02 br
00 or, a factor of 100 is a particular unit? 02 br

0 The mathematical term 'factor' means the numbers which can be multiplied together to reach the product; the number 12 has 8 different possible integers as factors (12 x 1; 6 x 2; 4 x 3). 02 br
02 br
00 $10,000 = 100 x $100. In this mathematical equation, '100' and '$100' are factors of '$10,000. 02 br
02 br
00 The costs will have to come down to $100 per pound.
