A boy wants to buy x apples in the shop. He has to pay y dollars for the first apple, 2y dollars for the second one and so on (in other words, he has to pay i x y dollars for the i-th apple). He has n dollars. How many dollars does he have to borrow from his friend to buy x apples? Instruction: Create a Java program that will perform the algorithm to compute for the amount of dollars that the boy must borrow from his friend using multilevel inheritance as shown in the figure. • Main class - Creates an instance of "Money" class and call Input the methods in sequence as shown in the figure. cost, dollar, num: Int • Input class - It contains a method in() that ask for three in() positive integers as an input which are the cost of the first apple, initial number of dollars the boy has, and number of apples he wants. • Cost class – It contains a method formulaC() that computes Main Cost obj.formulaC() 0: urlqo formulaC() obj.formulaM() for the total cost of the apples. • Money class - It contains a method formulaM() that computes and displays the amount of dollars that the Money boy must borrow. formulaM() Use comments to explain your codes.
