Write a post describing a good or service that either a compliment or a substitute

*Be specific in describing what different goods or services serve as a possible substitutes or compliments for the good or service you choose.
*Give at least one specific example of a good or service that is either a substitute or compliment to the good you choose.
*Explain what will happen to the equilibrium price and quantity of the good you choose if the price of the compliment or substitute good increases.

Example: Tea and coffee are substitutes. Both tea and coffee are caffeinated beverages that people consume when they want to feel more awake. If the price of tea was to increase significantly, the demand curve for coffee would shift to the right. That is, more people would want to buy coffee at each price as some consumers would switch from tea to coffee in response to the increase in price. The equilibrium price and quantity of coffee would both increase as a result of an increase in the price of tea.
