Assume A adults and C children were admitted.
Now we can set up equations from information given:
A+C=1200 (1)
A*$4.5 (total revenue collected from adults) + C*$2 (total revenue collected from children) =$3,597.50 (2)
From Equation 1, we get A=1200-C, replace A in Equation 2 with 1200-C:
(1200-C)*4.5+C*2=3597.50 =>5400-4.5C+2C=3597.50 =>1802.50=2.5C =>C=721, A=1200-721=479
Answer: on that day, 479 adults and 721 children were admitted.
