There are 30 spaces for each vehicle in a parking lot. A caravan takes up a total of 2 spaces of parking space. How many vehicles can still park if there are 3 caravans currently parking?
Let's think step by step below.
24
The three caravans used up 3x2 = 6 parking spaces in the parking lot.

Therefore, 30 - 6 = 24 vehicles can still park in the parking lot.
