Solve the problem.An airline charter service charges a fare per person of $450 plus $40 for each unsold seat. The airplane holds 75 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) = 75(450 + 40x) or 33,750 + 3000x B. R(x) = x(450 + 40x) or 450x + 40x2 C. R(x) = (75 - x)(450 + 40x) or 33,750 + 3000x - 40x2 D. R(x) = (75 - x)(450 + 40x) or 33,750 + 2550x - 40x2
