Solve the problem.A charter flight charges a fare of $300 per person plus $6 per person for each unsold seat on the plane. If the plane holds 176 passengers and if x represents the number of unsold seats, find an expression for the total revenue received for the flight. (Hint: multiply the number of seats sold, 
by the price per ticket).
A. R(x) = (176 - x)(300 + 6) B. R(x) = x(300 + 6x) C. R(x) = (176 - x)(300 + 6x) D. R(x) = x(176 - x)
