HOW DO YOU SEE IT? The graph below shows a company’s estimated profits for different advertising expenses. The company’s actual profit was $ 936 , 660 for an advertising expense of $ 300 , 000. (a) From the graph, it appears that the company could have obtained the same profit for a lesser advertising expense. Use the graph to estimate this expense. (b) The company’s model is P = – 140.75 x 3 + 5348.3 x 2 – 76 , 560 , 0 ≤ x ≤ 35 where P is the profit (in dollars) and x is the advertising expense (in tens of thousands of dollars).Explain how you could verify the lesser expense from part (a) algebraically.

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 = (4x / 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:
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?
