Hello Vjesus12.
Let's take a look at your question.
We know the following information:
(i) It costs g cents per mile for gasoline
(ii) it costs m cents per mile for all other costs to run a car
And we want to know how many dollars will it cost to run a car 200 miles?
Since the trip was 200 miles long, then the costs are $$200\cdot g\ \ \ \ and\ \ \ \ \ \ 200\cdot m$$ So, the total cost is $$C=200\cdot g+200\cdot m$$ Now $$C=200\cdot\left(g+m\right)\ \ \ cents$$ Now, the question asks for how many dollars, and since 200 cents = 2 dollars we get that the total cost is 2(g+m).
This is why the correct answer is the option E.
I hope it helps you. <i class="em em-smiley"></i>

A. 200m/g
B. 200gm/(g + m)
C. 200gm
D. 200(g + m)
E. 2(g +m)
(200g + 200m)/100 = 200(g + m)/100 = 2(g + m)

Hi VJesus12,
We're told that it costs G CENTS per mile for gasoline and M CENTS per mile for all other costs to run a car. We're asked for the number of DOLLARS it will cost to run a car 200 miles. This question can be solved in a couple of different ways, including by TESTing VALUES.
IF.... G=2 and M=3
The the cost to run a car for 200 miles would be (2)(200) + (3)(200) = 400 + 600 = 1,000 cents = $10.00
Thus, we're looking for an answer that equals 10 when G=2 and M=3. There's only one answer that matches...
Final Answer: E
