Originally, the quantity demanded and the quantity supplied for the commodity Z are 50 units and 80 units respectively when the selling price is 20 pesos per unit; 95 units and 60 units respectively when the selling price is 15.00 pesos per unit. Solve the following: 1. Derive the original and new demand and supply equations given that due to the increase in the buyer's income, the demand for this commodity increased by 10 units. 2. Solve for the price that caused a surplus of 5 units. Solve for the price that caused a shortage of 12 units. 3. Prove that the price equilibrium and the change in demand is directly related by computing the change in price equilibrium. Also prove that the quantity equilibrium and the change in demand are also directly related by computing the change in quantity equilibrium.

Gasoline prices have been and will continue to be a major issue for the economy. From the start of the Covid-19 pandemic up to the present day, gasoline prices have been in the news. ---What has happened to the price of gasoline over the past 12 months? Be specific and include actual prices in your answer. ---Discuss the recent changes in price from a supply and demand standpoint. Have the price changes been due to a change in supply, a change in demand, or both? Explain your answer. ---How did Covid-19 affected the market for gasoline? Which of the main influences of supply and demand do you think were responsible for the price changes? (See textbook pages 90-91 and 97-98.) Be specific and explain why and how the "main influences" you chose had an impact on the gasoline market.
Consider the market for product ABC, when the price is at Php 12, quantity demanded is 6 units and quantity supplied is 3 units. An eight pesos increase in the price would change quantity demanded by 2 units and quantity supplied by 4 units. How much is the gap at price of Php 11? A one peso decrease in the price of the product would _ quantity demanded by _ units.How much is the equilibrium price? How many units is the quantity supplied when price is zero?

Your analysis of data indicates that the demand curve for product x is estimated to be linear and given by equation Qd = 150-3p and the supply curve for product x appears to be linear as well and is estimated Qs=P-10. Graphically draw these two curves labeling all relevant points such as intercepts for each line inn the horizonal and vertical axes. Now, given the demand is Qd=150-3P and supply is Qs=P-10 the next assignment is to compute the equillirbium price and quantity in the market for product X, indicate on a graph. changes in consumer demographics cause the demand curve to change Qd=90-3p. If the supply curve remains the same Qs = P - 10 graphically draw these two curves labeling all the relevant points in the horizontal and vertical axes. Now, given the demand is Qd = 90-3P and supply is Qs = P-10, the next task is to compute the new equilibrium price and quantity in the market for product x. Indicate on a graph.

1. Suppose that a small, tropical country produces mangoes for domestic consumption and possibly for export. The national demand and supply curves for mangoes in this country are given by the following: P = 50 - M P = 25 + M (national demand) (national supply) where P denotes the relative price of mangoes and M denotes the quantity of mangoes (in metric tons). (a) Illustrate these relationships geometrically. What is the autarky price and quantity (b) exchanged? (c) Suppose that the world price of mangoes is 45. Will this small country export mangoes? If so, how many tons?
If the price per unit of good A is P175 quantity purchased is valued at 5,250 units and quantity supplied equals 2,500 units. If price changes by P1, quantity demanded changes by 4 units for consumer demand and quantity supplied changes by 2 units. Determine the demand and supply functions. Determine the price and quantity at equilibrium, using algebraic solution. Graph demand and supply curves on one set of axes and highlight the following: price-intercepts of demand and supply curves, quantity-intercepts of demand and supply curves, and the equilibrium point. (Make sure to LABEL your graph accordingly.)
