Could you please help?

The Christmas tree store has a parking lot that will hold 1000 vehicles. 2/5 of the parking spaces are for cars. When you went to buy your tree, there were 200 cars and some trucks in the parking lot. The parking lot was 3/4 full. How many trucks were in it?

Thank you

The parking lot can hold 1000 cars+trucks.

2/5 are for cars; therefore, 2/5 x 1000 = 400 spaces for cars.
The parking lot was 3/4 full so 3/4 x 1000 = 750 cars and trucks.
But there were 200 cars; therefore, the number of trucks must be 750-200 = ??
Check my thinking.

I checked and the answers is 500 trucks?

no its 550

NOT RIGHT !

Equation for Airport parking

To find out how many trucks were in the parking lot, we need to first determine the total number of vehicles in the parking lot.

Given that the parking lot can hold 1000 vehicles and it was 3/4 full, we can calculate the number of vehicles in the parking lot:
3/4 * 1000 = 750 vehicles

Now, we know that 2/5 of the parking spaces are for cars. So, we can find the number of car spaces:
2/5 * 1000 = 400 car spaces

Given that there were 200 cars in the parking lot, we can calculate the number of remaining vehicles:
750 - 200 = 550 remaining vehicles

As the remaining vehicles are assumed to be trucks, the number of trucks in the parking lot is 550.
