Do I need a topic sentence at the beginning of every paragraph?
When writing essays for tests and for most school work, it's a good idea to make sure every paragraph has a topic sentence that is found at the beginning. This makes is easier for a teacher or reviewer to understand what you are trying to say. However, this is not a firm rule. Transitions, flow, and more complex ideas can mean that the topic of a paragraph may need to be more than one sentence or found in the middle or end of a paragraph. Make sure you are writing to your audience and following their expectations.
What is quantitative easing?

How do I find the equilibrium price?
The equilibrium price in perfect competition is when the quantity demanded is equal to the quantity supplied. With quantity is on the x-axis and supply on the y-axis, supply is upward-sloping (quantity increases as price increases) and demand is downward-sloping (quantity decreases as price increases). The equilibrium price is found at the intersection of supply and demand.
