A. 35
B. 45
C. 55
D. 65

Answer 1

To find the number of vehicles that are not minivans, we need to calculate the number of minivans and subtract it from the total number of vehicles. According to the given information, for every 2 minivans, there are 5 other types of vehicles. Using this information, we can set up an equation and solve for the number of minivans. Finally, we subtract the number of minivans from the total number of vehicles to find the number of vehicles that are not minivans.

Step-by-step explanation:

To find the number of vehicles that are not minivans, we need to calculate the number of minivans and subtract it from the total number of vehicles. Let's say the number of minivans is 'x'. According to the given information, for every 2 minivans, there are 5 other types of vehicles. So, the number of other types of vehicles is 5x.

Now, the total number of vehicles is given as 161. Therefore, we can write the equation: x + 5x = 161.

Combining like terms, we get 6x = 161. Dividing both sides by 6, we find that x = 26.8. Since the number of vehicles cannot be a fraction, we can assume there are 27 minivans. Therefore, the number of vehicles that are not minivans is 161 - 27 = 134. Hence, the correct answer is 134 (C).
