When wild flower honey costs $4 a jar, 280 jars of wild flower honey are sold and 320 containers of hazelnut chocolate spread arc sold; when wild flower honey costs $3 ajar, 360 jars of wild flower honey are sold and 470 containers of hazelnut chocolate spread arc sold. For the organic almond milk with calcium (2L), suppose that its quantity demanded (QD) is represented by the equation, QD = (1, 960 + D_8) - 34P; and its quantity supplied (QS) is represented by the equation, QS = P, where P is the unit price for 2|L organic almond milk with calcium.
(a) Find the equilibrium price and quantity of the organic almond milk with calcium.
(b) Determine the values of QD and QS when the new unit price of organic almond milk with calcium is $38.
(c) Is there a surplus or a shortage in the market when the unit price of organic almond milk with calcium is fixed at $38.
(d) From the result obtained in part (c), determine if the unit price P will rise or fall in order to find the equilibrium point?
