I am currently computing the answers to 2-32 in my

Horngren, Charles T.. Introduction to Management Accounting (p. 69). Pearson Education. Kindle Edition. Textbook. I found the answers to the questions but I do not see any explanation as to how I compute them. Could you clarify how to calculate selling price per unit, variable cost per unit, total units sold, total contribution margin, total fixed cost, and net income? Thank you!
