Question

Suppose the current price of a good is $55. At this price, the quantity supplied is 165 units, and the quantity demanded is 240 units. For every $1 increase in price, the quantity supplied increases by 5 units and the quantity demanded decreases by 10 units. At the current price, the quantity demanded isgreater than the quantity supplied. This means that the market is currently experiencing asurplus . In order to adjust, the market price willincrease until the quantity demanded and quantity supplied are equal. The result is an equilibrium quantity of and an equilibrium price of $ .

Answer 1

Answer:

190

$60

Explanation:

Equilibrium price is the price at which quantity demanded equals quantity supplied

Equilibrium quantity is the quantity at which quantity demanded equals quantity supplied

Let x = change in quantity supplied

the following equations can be derived from the question

165 + 5x = total change in quantity supplied

240 - 10x = total change in quantity demanded

At equilibrium, quantity demanded equals quantity supplied. So,

165 + 5x = 240 - 10x

collect like terms and solve for x

15x = 75

x = 5

this means that quantity supplied would have to increase 5 times : 165 + 5(5) = 190

and quantity demanded would have to decrease 5 times : 240 + 10(5) = 190

equilibrium quantity is 190

equilibrium price = $55 + 1(5) = $60
