15 movie theaters average 600 customers per theater per day. If 6 of the theaters close down but the total theater attendance stays the same, what is the average daily attendance per theater among the remaining theaters?

Question

A. 750
B. 1000
C. 1200
D. 1500

Answer 1

the average will be total-attendance / #-theaters:
(15*600)/(15-6)

Answer 2

C/15 = 600,
C = 9,000 customers, total.
9000/(15-6) = 1000 customers = Average daily attendance per theater.
