Answer:
the number of minivans the dealership cells if it sells 35 cars is 20 minivans
Explanation:
We are given 
A car dealership sells seven cars far every four minivans
It means that 
4 minivans = 7 cars
or we can also write as
7 cars = 4 minivans
now, we can find for 1 car

now, we can multiply both sides by 35

now, we can simplify it 


So, 
the number of minivans the dealership cells if it sells 35 cars is 20 minivans
