Tickets to a basketball game can be ordered online for a set price per ticket plus a 5 dollars and 50 cents service fee. The total cost in dollars for ordering 5 tickets is 108 dollars Which linear function represents c , the total cost, when x tickets are ordered? (A service fee is a single fee applied to the total, no matter the number of tickets purchased).
Answer
A
c of x is equal to 5 point 5 0 x plus 20 point 5 0
B
c of x is equal to 5 point 5 0 x plus 21 point 6 0
C
c of x is equal to 5 point 5 0 plus 21 point 6 0 x
D
c of x is equal to 5 point 5 0 plus 20 point 5 0 x
Explanation
The single service fee is $5.50, so the five tickets themselves cost $108 − $5.50 = $102.50. Each ticket costs $102.50 ÷ 5 = $20.50. For x tickets, the total is $20.50x plus the one-time $5.50 fee, which matches choice A.
