Jim uses the function f(x) = 0.7x + 23 to determine the amount he charges for each useddrone he sells, where x is the original value of the drone. The function g(x) = 1.08x is used todetermine the amount a customer pays for a drone at Jim’s store including 8% sales tax.Write a function to determine the total amount a customer pays for a used drone at Jim’sstore including 8% sales tax.
