Create a function named fnTuition that calculates the tuition for a student. This function accepts one parameter, the student ID, and it calls the fnStudentUnits function that you created in task 2. The tuition value for the student calculated according to the following pseudocode: if (student does not exist) or (student units = 0) tuition = 0 else if (student units >= 9) tuition = (full time cost) + (student units) * (per unit cost) else tuition = (part time cost) + (student units) * (per unit cost) Retrieve values of FullTimeCost, PartTimeCost, and PerUnitCost from table Tuition. If there is no student with the ID passed to the function, the function should return -1. Code two tests: 1) a student who has < 9 student units, and 2) for a student who has >= 9 student units. For each test, display StudentID and the result returned by the function. Also, run supportive SELECT query or queries that prove the results to be correct.
Write a split_check function that returns the amount that each diner must pay to cover the cost of the meal. The function has four parameters: . bill: The amount of the bill. people: The number of diners to split the bill between. tax_percentage: The extra tax percentage to add to the bill. tip_percentage: The extra tip percentage to add to the bill. ● ● The tax or tip percentages are optional and may not be given when calling split_check. Use default parameter values of 0.15 (15%) for tip_percentage, and 0.09 (9%) for tax_percentage. Assume that the tip is calculated from the amount of the bill before tax. Sample output with inputs: 25 2 Cost per diner: $15.50 Sample output with inputs: 100 2 0.075 0.21 Cost per diner: $64.25 Learn how our autograder works 461710.3116374.qx3zqy7 1 # FIXME: Write the split_check function.

2. Safir Market wants you to create a simple python program for calculating Total cost and change for their customers. The program should start by reading price, articles and Money. Then you need to do the following: • Create a void function that will display "Safir Market" • Create a function with return value and with parameters that will compute Total cost as product of articles and price • Create a function that will accept the computed Total cost as a parameter and will compute the change. If the Total cost is more than or equal to Money, the balance is to be calculated as Money - Total cost, otherwise print the message 'Money not enough' • Display the output as shown below, Sample output Enter the price: 345 Enter number of articles: 4 Enter Money: 65 -Safir Market Total cost is: 1380.0 Money not enough Change is: None
