Question

She noticed that for every two minivans there were 5 other types of vechicles. If there are 161 people in the parking lot how many of them are not minievans

Answer 1

so 2/7 cars are minivans, 161/7=23, (23)2= 46, that mean there is 46 minivans so 161 cars - 46 minivans=115 cars that aren't minivans.
