Question

please help me I ill make brainlest answer if you get it right

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

Hey there!

So m=miles
 130= .5m+30
subtract 30 from each side
100$= .5m than divide .5 to isolate m
m= 200

I hope this helps!
