Answer:
Step-by-step explanation:
Rounding the answer is 100.
33 child tickets were sold that day.
adult tickets = a
child tickets = c
9.2a + 5.4c = 785.4
a = 2c
Substitute a into the first equation
9.2(2c) + 5.4c = 785.4
Simplify
18.4c + 5.4c = 785.4
Combine like terms by adding
23.8c = 785.4
Divide both sides by 23.8 to isolate the variable c
c = 33
