Question

In 2 or 3 sentences, explain why putting the demand and supply schedules together can help you to see what price and quantities will be demanded and supplied in the marketplace.

Answer 1

Answer;
By putting demand and supply schedules together, one can view the lowest price, that is where demand is greatest and supply is least, and at the highest price, where demand is least and supply is greatest.
Having these schedules together as a table, you are able to see the highest price and quantities that are acceptable for consumers to consider a demand.

Explanation;
Demand is the amount of goods and services the buyers are willing and able to buy at a given price. The demand curve shows the amount or quantity of goods and services bought at different prices.
A supply curve on the other hand shows the quantity of goods and services supplied at different market prices. 
By putting the two curves and schedules together one can determine the price and the quantities that will be demanded and supplied in the market.

Answer 2

Putting the demand and supply schedules together can help you to see what price and quantities will be demanded and supplied in the marketplace through giving you a clear picture of the data. By looking at both, you can already compare how much of the supply and demand of the good and see a clear picture of the relationship between the two and how they affect each other with respect to each other.
