D. (4 points) A movie theater sells 4 different priced tickets: youth, adult, senior, student. Below is a matlab function called "tickets" that has 2 vectors as arguments: the first vector has the price of each type of ticket in dollars and the second vector has the of each type of ticket sold for a group of customers. The function returns the total ticket income and the total number of tickets sold. function income cnt l tickets price numTickets income price numTickets; income sum (income) cnt sum (num rickets) end [total Income totalCount] tickets [3 10 6 5 [1 3 1 21) total Income 49 total count. 7 a. The theater has decided to add a special discount. Customers get a percentage off equal to the number of people in their party. Add code to the above function for that modification. b. The theater is also trying a different special discount. If there are more than 5 customers of a type (youth, adult, senior, student), one customer of that type gets in free. Create a test table for each of these seperate modifications, and create two matlab functions to solve the problem. Design will be done in lecture or lab. Sample Data Expected Result verified?
