Rewrite the equation below to express the cost (c) as a function of miles (m). the charge for a rental car is $20 plus $0.05 per mile. cost = $20 + $0.05m rewrite the above equation in function notation using m.

The correct answer is:

c(m) = $20 + $0.05m.

Explanation:

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.
