Answer:

52 adults

Explanation:

Let 'a' represent the number of adults at the movies. Then the number of children is (140-a) and the amount collected is ...

2.70(140-a) +5.25(a) = 510.60

2.55a +378 = 510.60 . . . . . . . . . simplify

2.55a = 132.60 . . . . . . . . . . . . subtract 378

a = 52 . . . . . . . . . . . . . . . . . . divide by 2.55

There were 52 adults at the movies.
