Solve the problem.An airline charter service charges a fare per person of $350 plus $20 for each unsold seat. The airplane holds 100 passengers. Let x represent the number of unsold seats and write an expression for the total revenue R for a charter flight.
A. R(x) = (100 - x)(350 + 20x) or 35,000 + 2000x - 20x2 B. R(x) = x(350 + 20x) or 350x + 20x2 C. R(x) = (100 - x)(350 + 20x) or 35,000 + 1650x - 20x2 D. R(x) = 100(350 + 20x) or 35,000 + 2000x
