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?
a. c(x) = 5.50 + 20.50x
b. c(x) = 5.50x + 20.50
c. c(x) = 5.50 + 21.60x
d. c(x) = 5.50x + 21.60

D. c(x) = 5.50x + 21.60

Step-by-step explanation:

For a ticket ordered, there is always $5.50 service fee

x tickets ordered with a service fee of $5.50 will be $5.50x (1)

Also if the total cost of ordering 5 tickets is $108.00

Total cost of ordering x tickets will be;

5tickets = $108.00

x tickets = ?

? = #108.00x/5

? = $21.60

The total cost of 5tickets will be $21.60 (2)

The linear function c(x), when x tickets are ordered will give us the sum of the two equations above

c(x) = 5.50x + 21.60 (D)

answer:

c) the x-coordinate of the center of the circle increases by 3
