Create a spreadsheet listing the number of credit hours you have taken in college so far. Also determine the amount of money spent on tuition, textbooks, and any other items directly related to studying the course. Then, compute the average cost per credit hour. Be sure to include a brief narrative/summary of your information. Use this exercise to practice making a spreadsheet and using formulas. You will be graded on the correctness of your formulas. The end result of your spreadsheet will be the average cost per credit hour for your education so far
