Answer provided by our tutors
let
c = the number of child tickets sold
a = the number of adult tickets sold
twice as many adult tickets as child tickets were sold, for a total sales of $462.00
a = 2c
5.30c + 8.90a = 462
by solving the system of equations
a = 2c
5.30c + 8.90a = 462
we find
c = 20 child tickets
