Question

If C(m) = 0.50m + 30 represents the cost of renting a car, how many miles were driven if the cost is $130?

50 miles
80 miles
200 miles
320 miles

Answer 1

The cost is $130, so we can set up the equation as follows:

130 = 0.50m + 30

Subtract 30 from both sides:

100 = 0.50m

Now, divide by 0.50 on both sides:

m = 200

Therefore, 200 miles were driven.

So, the correct answer is:

200 miles
