Question 23622: I have the following word problem and I think the answer is 2 but I do not know how to write the equation. Can you help? Thank you.
A car dealer has 22 vehicles on his lot. If 8 of the vehicles are vans and 6 of the vehicles are red and 10 vehicles are neither vans nor red, how many red vans does he have on his lot?
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! 10 of the 22 are neither vans nor red.
That leaves 12 that may be van, red, or red-vans
8 of the 12 are vans, some of which may be red
That leaves 4 that are strickly red.
But you were told there are 6 red vehicles.
Two of those red vehicles must be vans.
cheers,
Stan H.
