Question

A bike rental company charges $10 plus a charge per for the distance ridden. the total cost, t, can be represented by the equation t=10+cm , where c is the additional cost per mile and m is the number of miles ridden. solve the equation for c.

Answer 1

Answer:

$c=\frac{t-10}{m}$

Step-by-step explanation:

$t=10+cm$

Subtract 10 from both sides:

$t-10=cm$

Divide both sides by $m$:

$\frac{t-10}{m}=c$

Placing $c$ on the left:

$c=\frac{t-10}{m}$

For example, if the total charge is $27.50 and the distance ridden is 250 mi, we can calculate the additional cost per mile, as such:

$c=\frac{27.50-10}{250}$

$c=0.07$
