15% of 7,000 pageviews on NatuRun, which have the original article from SciFun, resulted in users clicking the link to the original article on SciFun. So, the number of pageviews from NatuRun to SciFun is 0.15 x 7,000 = 1,050. 
The original article on SciFun generates 147,000 hits; therefore, the number of hits generated on the original article due to NatuRun is 1,050 x 20 = 21,000. However, the question asks for the number of hits generated on the original article due to NatuRun, not total hits. So, we subtract the 20 hits to get the final answer, which is 21,000 - 20 = 22,050.
