Answer :
If Shen produced and Manuel consumed one additional bottle of water, total surplus would be $2
What is the law of Supply and Demand?
The law of supply and demand combines two fundamental economic ideas that describe how changes in the price of a resource, commodity, or product affect its supply and demand.
Supply grows as the price rises, but demand drops. In contrast, as the price falls, supply is constrained and demand is increased.
Demand and supply levels for different prices can be displayed as curves on a graph. The intersection of these curves symbolizes the process of price discovery in the marketplace, as it indicates the balance, or market-clearing price, at which demand equals supply.
According to the law of demand, demand for a good or resource will decrease as its price increases and increase as its price decreases.
How to solve?
Price ------ Quantity Supplied ----- Quantity Demanded
2 --------------------- 1 ------------------------- 3
4 --------------------- 2 ------------------------ 2
6 --------------------- 3 ------------------------ 1
4 (quantity supplied = quantity demanded = 2)
4 ($7>$4 and $5>$4, $3<$4<$5, area above price line but under curve if price line was at $4, $7-$4=$3, $5-$4=$1, $3+$1=$4); 4 ($1<$4 and $3<$4, $3<$4<$5, area below price line and under curve if price line at $4, $4-$1=$3, $4-$3=$1, $3+$1=$4); 8 ($4 from consumer surplus + $4 from producer surplus)
fall (equilibrium = 2, 2-1=1, Shen: quantity supplied = 1 -> $2, Manuel: quantity demanded = 1 -> $6, total surplus = producer surplus + consumer surplus = ($4-$1)+($7-$4)=$6, $8>$6)
rise (equilibrium = 2, 2+1=3, Manuel: quantity demanded = 3 -> $2, Shen: quantity supplied = 3 -> $6, total surplus = consumer surplus + producer surplus = ($3-$2)+($7-$6)=$2, $8>$2, $6>$2)
