Tickets to a basketball game can be ordered online for a set price per ticket plus a $5.50 service fee. The total cost in dollars for ordering 5 tickets is $108.00. Which linear function represents c, the total cost, when x tickets are ordered?

• c(x) = 5.50 + 20.50x

• c(x) = 5.50x + 20.50

• c(x) = 5.50 + 21.60x

Which equation represents a line that passes through (2, –1/2) and has a slope of 3?
