Step by step if c(m)=0.50m + 30 represents the cost of renting a car, how many miles were driven if the cost is $130

200 miles were driven

Step-by-step explanation:

We know that represents the cost of renting a car

Where m represents the number of miles driven

If we know that the cost was $ 130 then we can equal C(m) to 130 and solve for m.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
