The number of adults tickets sold, a, was eight times the number of child tickets sold, c,.
Child tickets cost $2.50 each; adult tickets cost $5.00 each and last night's show brought in $850.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can solve the problem mentally, without using equations.
HINT: You can group the tickets in sets in a way each set contains 8 adult tickets and 1 child ticket.
Then each set is worth 8*5 + 2.50 dollars = 42.50 dollars, and the number of sets is  = 20.
Did you get the idea ?
