Answer:
Step-by-step explanation:
The percentage of high school students who drink and drive at the beginning of 2001 = 17.5%
The percentage of high school students who drink and drive at the beginning of 20011 = 10.3%
Rate of decrease = 17.5 - 10.3 / 10
= .72
The required linear function
f(t) = - 0.72 x t + 17.5
b ) Rate of decrease in percentage = (17.5 - 10.3) / 10
= .72 %
c ) Percentage of high school students who drink and drive at the beginning of 2014
t = 2014 - 2011 = 13
f(t) = - 0.72 x t + 17.5
= - .72 x 13 + 17.5
= 8.14 %
