Question

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.

Answer 1

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.

Answer 2

Answer:

Required equation in function form is $c(m)=\ 20+0.05m$

Step-by-step explanation:

Given : The charge for a rental car is $20 plus $0.05 per mile. cost = $20 + $0.05m.

To find : Rewrite the above equation in function notation using m?

Solution :

The charge for a rental car is $20 plus $0.05 per mile.

Let the cost of a function represent as- c

Let the per mile represent as - m

We have given, cost = $20 + $0.05m.

Since cost is a function of miles,

So, We can write the above situation as

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

Which represent the cost of rental car changes according to mile car cover.

Therefore, Required equation in function form is $c(m)=\ 20+0.05m$
