CMSC 104, Summer 2009

Homework 2

Basic Algorithms

Out: Monday 6/8/09
Due at the beginning of the class period: Monday 6/15/09
Note that late homeworks will NOT be accepted.

The Objectives

To practice solving problems in a generic manner
To practice writing basic pseudocode for the solution of a problem

The Assignment

The answer to each problem will have two parts: the specific solution and the general solution.
You do not have to do any error checking of user input.
First solve each of the two problems shown below. You should show the specific answer to the problem using the numbers given. (25 points each, so make sure you show your work, no matter how simple you think it is)
Then write an algorithm for each of these two problems in pseudocode.(25 points each)
1. Mrs. Smith is on a cruise to the Bahamas. On a rainy day, she decides to go to the casino bar and play blackjack. She pays a $5.00 cover charge to enter the casino bar. She plays at one table, doubles her money and tips the dealer $10.00. She goes again the next day, pays a $5.00 cover charge and doubles her money. After tipping the dealer $10.00, she runs out of money. How much money did she start with?
2. Your grade in CMSC104 is based on the following:
```
 
 
 3 Homeworks (4% each) = 12%
 4 Projects  (7% each) = 28%
 3 Exams    (20% each) = 60%
 
 Total = 100%
            
```
  If you have the following homework, project and exam grades at the end of the semester, calculate your final grade for the course:
```
 
  Homework 1 = 100/100  Project 1 =  85/100    Exam 1 = 95/100
  Homework 2 =  50/100  Project 2 =  75/100    Exam 2 = 80/100
  Homework 3 = 100/100  Project 3 =  75/100    Exam 3 = 70/100
                        Project 4 =  80/100
                    
```
  Tips about problem # 2 :
  - You should allow the user to enter in each of the homework, project and exam grades.
  - You can assume the percentages will always be 4%, 7% and 20%. You should not ask the user to enter in these values.
