Question
If C(m)=0.50m+30 represents the cost of renting a car, how many miles were driven if the cost is $130?Responses320 miles320 miles80 miles80 miles200 miles200 miles50 miles
Solution
To find out how many miles were driven if the cost is $130, we need to set C(m) equal to 130 and solve for m.
The equation is C(m) = 0.50m + 30.
First, subtract 30 from both sides of the equation to isolate the term with m:
0.50m = 130 - 30 0.50m = 100
Then, divide both sides by 0.50 to solve for m:
m = 100 / 0.50 m = 200
So, 200 miles were driven if the cost is $130.
