The data for bachelor's degrees can he described by the following mathematical models:
a. According to the first formula, what percentage or bachelor's degrees were awarded to men in 2003? Does this underestimate or overestimate the actual percent shown by the bar graph? By how much?
b. Use the given formulas to write a new formula with a rational expression that models the ratio of the percentage of bachelor's degrees received by men to the percentage received by women n years after 1989 Name this new mathematical model R, for ratio.
c. Use the formula for R to find the ratio or bachelor's degrees received by men to degrees received by women in 2014. According to the model, how many women received bachelor's degrees for every two men in 2014? How well does this describe the data shown by the graph?
