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
