Final answer:
The total number of spectators is 1040.
Step-by-step explanation:
Let's denote the number of female spectators as 'F' and the number of male spectators as 'M'.
According to the given information, we have two equations:
M = F + 720
F = (2/11)M
Substituting the value of F from the second equation into the first equation, we get:
M = (2/11)M + 720
M - (2/11)M = 720
(9/11)M = 720
M = (11/9) * 720 = 880
Substituting the value of M into the second equation, we can find F:
F = (2/11) * 880 = 160
Therefore, the total number of spectators is the sum of M and F:
Total number of spectators = 880 + 160 = 1040
