Question

At the movie theatre, child admission is $5.60 and adult admission is $9.10 . On Tuesday, twice as many adult tickets as child tickets were sold, for a total sales of $499.80 . How many child tickets were sold that day?

Answer 1

5.60x+ 2(9.10)X= 499.80
23.8x= 499.80
Divide by 23.8
X= 21
21 children tickets

5.60(21)+ 42(9.10)= $499.80
