Remaining 7307

At the hockey match, the stadium was full at the beginning. After the first period, 20% of the fans left; after the second period, one-sixth of the remaining fans left. How many fans were in the stadium at the start of the match if 700 stayed until the end?

Correct answer:

n =  1050

Step-by-step explanation:

0.20 n + (n-0.20n)/6 + 700 = n

0.20·n + (n-0.20·n)/6 + 700 = n

4n = 4200


n = 4200/4 = 1050

n = 1050
