1. [25 pts.] Prepare a use case scenario for the "vacation time case including at least three options using the template given in the slides of the corresponding chapter. 2. [25 pts.] Draw a UML activity diagram using the scenario prepared for the vacation time case. 3. [25 pts.] Draw a Level 0 DFD for the vacation time case that shows what to do when you choose one of your options for taking a vacation. 4. [25 pts.] In this question, you must use your Student ID which has seven digits. Now, follow the below steps to build your question: If your ID begins with zero, then replace the first digit by five (ex: If your ID is 0735691, then use 5735691). The development cost of the target application is estimated as the value equivalent to twice the last five digits of your ID (ex: If your ID is 1728304, then your development cost estimation is 56608). The lifetime of the target application is five years. The operation cost of each year is estimated as the value equivalent to six times the first four digits of your ID (ex: If your ID is 1728304, then your development cost estimation is 10368). The benefit derived from the execution of the target application for each year during its lifetime is estimated as the value equivalent to twice the first five digits of your ID (ex: If your ID is 1728304, then your benefit estimation for each year is 34566). The return rate of the other investments will probably be the value equivalent to the last digit of your ID (ex: If your ID is 1728304, then the return rate estimation is 4%). If the last digit of your ID is zero, then take the return rate as 6%. Use two-digit precision in your calculations and estimate if the new application pays for itself. If the answer is yes, when will it pay for itself? 1.
