Question 271184
Movie tickets for an adult and three children cost $20. An adults ticket cost $2 more than a childs ticket. Find the cost of the adult's ticket.
-----------------------
Equations:
A + 3C = 20
A = C + 2
---------------------
Substitute into the 1st equation and solve for "C":
(c+2) + 3c = 20
4c = 18
c = 9/2
c = $4.50 (cost for a child's ticket)
-----
Since A = C+2, A = 4.50+2 = 6.50 (cost of an adult ticket)
