the high school band was selling ride tickets for the fair. On the first day, 200 child tickets and 100 adult tickets were sold for a total of $400. On the second day, 40 child tickets and 10 adult tickets were sold for a total of $60. What is the price for each child ticket and each adult ticket?

It would be 1$ per child and 2$ per adult.

Because that would mean on the first day there were 200$ worth of child tickets sold (200x1) and 200$ worth of adults tickets sold (100x2).

This would also work for the second day where 40$ worth of child tickets would be sold and 20$ worth of adult tickets are sold.

The child tickles would be $1 while the adult ticket would be $2
