Explanation / Answer
i)
The quantity demanded and supplied are equal at $6/gallon.
Equilibrium Price = $6
Equilibrium Quantity = 125gallons.
ii)
At $8/gallon, the quantity demanded is 75gallons while quantity supplied is 175gallons.
Hence, a surplus of 100gallons exists.
iii)
At $4/gallon, the quantity demanded is 175gallons while quantity supplied is 75gallons.
Hence, a shortage of 100gallons exists.
iv)
If there is an increase in supply, with demand being constant, the equilibrium price of gasoline would fall while the equilibrium quantity would increase.
