Answer:
0.903
Step-by-step explanation:
Given : 2D + 1L = 100,
And D + L = 70
This is a simultaneous equation can be solved as follows
2D + L = 100
- D - L = -70
————————————-
D - 0 = 30
i.e D (number of dudes) = 30
Therefore, since we already know the fraternity sold 70 tickets in total,
70 -30 = 40 (the number of ladies attended)
