Solve the problem.An airline charter service charges a fare per person of $350 plus $30 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 - x)(350 + 30x) or 26,250 + 2250x - 30x2
B. R(x) = 75(350 + 30x) or 26,250 + 2250x
C. R(x) = (75 - x)(350 + 30x) or 26,250 + 1900x - 30x2
D. R(x) = x(350 + 30x) or 350x + 30x2
