Grade Inflation. The bar graph shows the percentage of U.S. college freshmen with an average grade of A in high school. The data displayed by the bar graph can be described by the mathematical model p = 4 x 5 + 25 , where x is the number of years after 1980 and p is the percentage of U.S. college freshmen who had an average grade of A in high school. Use this information to solve Exercises 97-98 . a. According to the formula, in 2010, what percentage of U.S. college freshmen had an average grade of A in high school? Does this underestimate or overestimate the percent displayed by the bar graph? By how much? b. If trends shown by the formula continue, project when 57% of U.S. college freshmen will have had an average grade of A in high school.
