Credit hour is simply the number of hour a student must dedicate to classes per week.
<em>The student should take not more than 7 credit hours.</em>
From the question, we have the following observations:
- The student is working class
- The student wants to have a high grade point average
- The student wants to graduate as early as possible
The standard credit hour for working class students in an institution is usually 3 to 6 hours.
This can be represented as: <em>Not more than 6 hours</em>
From the complete question, the closest credit hours to <em>"not more than 6 hours"</em> is <em>"not more than 7 hours"</em>
Hence, the student should take not more than 7 credit hours

Answer:
The starting number is 78.
Explanation:
(x / 3) / 2 = 13
divide a number by 3 (x / 3)
divide in half (x / 3) / 2
You get 13 (x / 3) / 2 = 13
Reverse the problem.
13 * 2 = 26
26 * 3 = 78
x = 78
Plug in the number.
(78 / 3) / 2 = 13
78 / 3 = 26
26 / 2 = 13
