according to the law of supply:

Supply refers to the quantities of goods and services that suppliers are willing to sell in the markets at a specific price. The law of supply asserts that as price increases, suppliers will be willing to supply more products and services in the market. Producers or suppliers are business people; hence profit-motivated.

High prices imply suppliers will have bigger margins on products, which translates to profits. The supply curves illustrate the relationship between price and quantity supplied. The supply curve slopes upwards, showing how quantities supplied increase as prices rise.
