[tex]15000= \frac{5}{7}*x[\tex]
[tex]x=15000* \frac{7}{5}=21,000[\tex] 

Check 21,000 * 2/7 = 6.000 and 6,000 + 15,000 = 21,000

2/7 purchased 1000...therefore, 5/7 purchases 500...and 5/7 is 15000 people.
so 5/7 of what = 15000
5/7x = 15000
x = 15000 * 7/5
x = 105000/5
x = 21000 people viewed the concert
