Answer:

3.1 (nearest tenth)

Step-by-step explanation:

Year (independent variable) = x

Percent of adults (dependent variable) = y

Rate of change is given as = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex].

Let,

[tex] (1989, 20) = (x_1, y_1) [/tex]

[tex] (2007, 76) = (x_2, y_2) [/tex]

Plug in the values into the equation

Rate of change = [tex] \frac{76 - 20}{2007 - 1989} [/tex]

Rate of change = [tex] \frac{56}{18} = 3.1 [/tex] (nearest tenth)
