Correct Answer: C
Explanation:
(C) The value of m must be 2. All of the trucks and SUVs must add up to a total of 45, and there are 43 of the other truck/SUV types: 43 + 2 = 45. The value of n must be 13. The total of all the different types of vehicles must add up to 200. The numbers in the last column show a total of 178 + 9 = 187 and 187 + 13 = 200.
