Solve the problem.An airline charter service charges a fare per person of $250 plus $20 for each unsold seat. The airplane holds 175 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) = (175 - x)(250 + 20x) or 43,750 + 3250x - 20x2
B. R(x) = 175(250 + 20x) or 43,750 + 3500x
C. R(x) = x(250 + 20x) or 250x + 20x2
D. R(x) = (175 - x)(250 + 20x) or 43,750 + 3500x - 20x2
