Problema Solution
If the supply and demand equations for computers are D = 100−6p and S = 28+3p where p is the price of computers, what is the quantity of computers bought and sold at equilibrium.
Answer provided by our tutors
Equilibrium is defined to be the price-quantity pair where the quantity demanded is equal to the quantity supplied that is
D = S
100 - 6p = 28 + 3p
100 - 28 = 3p + 6p
9p = 72
p = 8 is the price of each computer
the quantity of computers is 100 - 6*8 = 100 - 48 = 52 computers.
