Answer:
The quantity demanded at $3 would be 18 units.
Explanation:
The market demanded curve is the sum of all individual demand curves in the market. We can sum up the individual quantity demanded of a good to find out the quantity demanded by the market as a whole.  
Suppose the price of a good is $3. There are three consumers in the market.
The first consumer would buy 6 units, the second would buy 5 units and the third would buy 7 units.
The market demand for the good at the price of $3 would be,  
= 6 units + 5 units + 7 units
= 18 units
 
        
             
        
        
        
The answer is A) Raising taxes
The Constitution of 1789 gives the Federal Government authority to raise and levy taxes in all of the States in America.
It comes under the General Welfare Clause and gives complete authority to impose and collect taxes. 
It prohibits separate State taxation IF it hinders inter State and International trading. It also prohibits each State from setting up independent import and export duties without the approval of the Federal Government, that is, the Congress.
It requires all tax revenue bills to originate solely from the House of Representatives.
