I'm guessing you want an equation that expresses the cost of any variable number of adult and children's tickets. Otherwise, it would not be algebra!

The expression we want is

#T=16A+8C#

using #T# for the total cost, #A# for the number of adults and #C# for the number of childran..

Let A represent the number of adults attending, and C be the number of children.

Since each adult pays $16, "A" adults would pay 16A dollars. Similarly for children; since each pays $8, C of them would pay 8C dollars.

The expression we want is

#T=16A+8C#

using #T# for the total cost.

With the numbers stated above, 3 adults and 8 children would cost

#T=16(3) + 8(8)=48 + 64=112

$112 for this group.
