Concert Tickets: Tickets for a concert cost $10 each if you order them online, but you must pay a service charge of $8 per order. The tickets are $12 each if you buy them at the door on the night of the concert, with no service charge.
a. Write a system of equations to model the situation. Let c be the total cost. Let t be the number of tickets.
b. Graph the equations and find the intersection point.
