Question

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

Answer 1

Answer:

200 miles were driven

Step-by-step explanation:

We know that $C (m) = 0.50m + 30$ 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.

$C(m) =0.50m + 30=130$

$0.50m + 30=130$

$0.50m=130-30$

$0.50m=100$

$m=\frac{100}{0.50}$

$m=200\ miles$
