Late homeworks will NOT be accepted. Make sure that you put your name and student id on your paper. If you have multiple sheets, staple them together.

Assignment:

1. First, solve each of the two problems shown below. You MUST show your work, no matter how simple you think the problems are. (5 points each)

2. Next, write an algorithm for each of the problems in pseudocode. Be consistent in style (e.g., use "Get" and "Display") when writing the pseudocode. Remember to indent any selection or repetition control structures. Also remember to make the algorithms generic. (10 points each)
   1) Sarah's grades on her four CMSC 104 projects were 94%, 82%, 75%, and 96%. She needs to compute her project average and then determine the corresponding letter grade based on the following scale: 90.0 <= average <= 100.0 A 80.0 <= average < 90.0 B 70.0 <= average < 80.0 C 60.0 <= average < 70.0 D 0.0 <= average < 60.0 F What is Sarah's letter grade for the average of her projects?

   The generic algorithm can assume that there will always be exactly four project grades. The grades should be retrieved from the user one at a time. The numeric average and corresponding letter grade should be displayed.

   2) A manufacturer sells a certain article to dealers at a rate of $10.00 each if less than 20 are ordered. If 20 or more are ordered, the price of each and every article is reduced by 50 cents. What is the total cost of 100 units?

   The generic algorithm should allow for changes in the $10.00 price and for purchases under 20 units. The algorithm should also allow for changes in the 50 cent reduced rate. All input should be retrieved from the user. The number of articles ordered and the total price should be displayed.
