Calculate the average score of three students with scores 75, 88, and 92.

Here are the answers to the problem:

A) Identify Inputs:

1. The pieces of information needed to start are the scores of the three students: Student A's score (75), Student B's score (88), and Student C's score (92).

B) Identify Output: 2. The final result to achieve is the average score of the three students.

C) Decompose the Calculation: 3. The basic arithmetic steps involved in finding an average are:

• Sum all the individual scores.
• Divide the sum by the total number of scores.

D) Design the Algorithm (Step-by-step procedure): 4. The steps for calculating the average score are:

• Step 1: Get Student A's score, which is 75.
• Step 2: Get Student B's score, which is 88.
• Step 3: Get Student C's score, which is 92.
• Step 4: Add the three scores together: $75 + 88 + 92 = 255$.
• Step 5: Divide the sum (255) by the number of students (3): $\frac{255}{3} = 85$.
• Step 6: The average score is 85.
