Explain how supply and demand affects consumers and businesses

If a product is in high demand the supply has to go up which can increase prices because of the demand.

The higher the demand for any good or service, the more the supplier can charge.For example, gas is a necessity, so the supplier can exploit our need for it by making us pay whatever they want we are their Mercy.If has was not a necessity and we do without it, it would be a lot cheaper.
Business succeed when they give the consumer what they want or need.The better the product/greater the need, the more of a desired object it is and the business can take liberty at raising the price.
Products that are not as desirable, for whatever reason, don't have such a "pull" for price hikes.
