Some water sports are expensive. People with larger incomes are more likely to participate in such a sport. The number of people N (measured in thousands) who engage in a particular water sport can be described by the function N=0.13x² -3.16x + 102.25, where x is the mean income (measured in thousands) and x ≥ 20. Use this information to find N when x = 25, x = 50, x= 75, x = 100, and x = 125. Find N when x = 25, x = 50, x=75, x= 100, and x = 125. When x = 25, N= 104.5 thousand people. When x = 50, N= 269.25 thousand people. When x = 75, N= 596.5 thousand people. When x= 100, N= 1086.25 thousand people. When x = 125, N= thousand people.
