Solve the problem.In a certain city, the cost of a taxi ride is computed as follows: There is a fixed charge of $2.80 as soon as you get in the taxi, to which a charge of $2.30 per mile is added. Find an equation that can be used to determine the cost, C, of an x-mile taxi ride.
A. C = 2.80 + 2.30x
B. C = 5.10x
C. C = 2.30 + 2.80x
D. C = 3.60x

Solve the problem.At $12 per ticket, the Casper Coyotes will fill all 6000 seats in the assembly hall. The manager knows that for every $1 increase in the price, 300 tickets will go unsold. Write the number of tickets sold, n, as a function of the ticket price, p. How much money will be taken in if the tickets are $21 each?
A. n(p) = -300p - 6360, -$12,660 B. n(p) = 600p + 4200; $16,800 C. n(p) = -300p + 9600; $3300 D. n(p) = -600p - 15,600; -$28,200
