In 2018 , the citizens of a country spent a total of \( \$ 73.6 \) billion on their pets. In 2015 , the citizens of the same country spent \( \$ 66.79 \) billion on their pets. Let \( y \) be the amount spent by those citizens on their pets in year \( x \), where \( x=0 \) represents the year 2015 . a. Write a linear equation that models the amount the citizens of the country spent on their pets in the year \( x \). [Hint: The line must pass through the points \( (0,66.79) \) and \( (3,73.6) \).] b. Use this equation to predict the amount citizens spend on their pets in 2027 .

The cost of renting a car for a day is given by the linear function \( C(x)=0.4 x+21 \), where \( C(x) \) is in dollars and \( x \) is the number of miles driven. Use this information to answer the questions below.

Determine the difference quotient \( \frac{f(x+h)-f(x)}{h} \) \( f(x)=4 x-8 \)

4) \( (-4)+2 \)
