No company can afford to build cars (supply them) if the sales price is only $1.  But at a sales price of $30,000, a vast number of cars can be built.  '''''The cause is price, and the effect is quantity.'''''

The demand for a good is also described in terms of price and quantity.  At a given price, there is a specific quantity in demand by the public for the good.  A billion people might buy a car if the price were only $1 (unrealistic).  At a much higher price of $30,000, the demand drops to a quantity of only millions sold (realistic).  At a still higher price of $100,000, the demand falls much further to the range of only a few thousand that can be sold (these are the very luxurious cars, like the Lamborghini sports car).
