Answer:
T=16A+8C using T for the total cost, A for the number of adults and C for the number of childran..
Explanation:
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.
