After expanding the expression by using distribution, you get P + Pr. Since r is the rate an item is taxed by, the term Pr expresses the additional amount that you have to pay in tax. Pr is the answer. I hope this helped!

Step-by-step explanation:
<span>The <u>correct answer</u> is:
c(m) = $20 + $0.05m.
Explanation<span>:
To write in function notation, we use a variable, c, to represent cost, and our variable m to represent miles.
Since cost is a function of miles, we write c(m), which we read as "c of m", in place of y.
Everything else in the equation stays the same, as the relationships between the numbers and variables does not change.</span></span>

Step-by-step explanation:
A graphing calculator can do a nice job of showing you what the graph looks like.
The initial factor of 4 is the value when x=0, the y-intercept. The base of 2 tells you the function value is multiplied by 2 for each unit of x to the right, and divided by 2 for each unit of x to the left. (The curve quickly goes off the top of the graph.)
The horizontal asymptote is y=0, as it is for all exponential functions (that have not been translated).
