Question

Please can anyone help me

. A rental moving company charges a flat rate of $15 and an additional $0.50 per mile for moving services. Which linear function represents the total charge f for x miles?
1 . f(x) = 15x + 0.5
2. f(x) = 0.5x – 15
3. f(x) = 0.5x + 15
4. f(x) = 15x – 0.5

Answer 1

f(x) = 0.5x + 15

Explanation:

Here, we want to get the total charge

From the question;

we have a flat rate of $15

now, $0.5 per mile for x miles will be a charge of 0.5 * x = $0.5x

We now add this to the flat fee to get the total score

That will be;

f(x) = 15 + 0.5x
