2. Suppose you are making some soup. You have 7 types vegetables in front of you (one serving of each) and you want to include 4 of them in your soup (each being different). How many ways are there to do this?

3 different ways to do it.

70 vehicles

Step-by-step explanation:

To solve this problem, you take the number of items there are (pickup trucks in this case) and divide it by the percentage of those items (20%).

14 / 20% = 14 / (20/100) = 14/0.2 = 70

We can check by taking 20% of 70 and seeing if it is 14:

.2 * 70 = 14

We are correct. Thus, the total number of vehicles is 70.
