According to data from the National Center for Education Statistics, the average tuition for a four-year degree program in 1982 was $3,429. When adjusting for inflation, this amount would be equivalent to $8,677 in 2007 dollars. However, the actual average tuition in 2007 was $18,632 – an increase of approximately 215% in nominal terms, or 215/8.677 = 24.8 times. When adjusted for inflation, the increase is approximately 400% (18,632/8,677), which makes option C the correct answer.
