QUESTION 10 If you have $47,000 in student loans at an interest rate of 5%, compounded monthly, what is the monthly payment necessary to pay them off over the next 20 years? QUESTION 11 If the demand equation is D(x) = 109 - 3.9x and the supply equation is S(x) = 6.3x + 35, find the equilibrium quantity.

Given a demand curve of P = 165 - 6Qd and supply of P = 65 + 5Qs, find the equilibrium price (Pe), AFTER lower input costs have shifted supply by 4 dollars.

The market for gravel has the following demand and supply relationships: Supply function: Q = 100P - 1,000 Inverse demand function: P = 50 - 0.01*Q + PX, where P represents price of gravel per ton in dollars, Q represents sales of gravel per week in tons, and PX is the price of some other product X in dollars per unit. Let PX = $50/ton In a diagram, qualitatively describe the change that would occur in the market for gravel (i.e. equilibrium price and quantity) if a new discovery has just made the production of product X cheaper. Briefly explain whether it is a movement along or shift of demand curve and supply curve for gravel. In addition to the new discovery regarding product X in previous question), suppose now workers producing gravel ask for sick leave due to COVID. Use supply and demand analysis to predict how these two shocks will affect equilibrium price and sales. Illustrate your results in a diagram. Is there enough information to determine if market prices will rise or…

If the demand equation of a product is p= 210-g and the supply equation for a product is p= 29+2 then, the equilibrium price equals

Assume that the supply and demand equations for 1-shirts at store A and 2 in a particular week are. = .7q+ 3 offer p= - 1.7q + 15 Demand Determine the equilibrium quantity and price that stabilizes the T-shirt market. (1) (4$5.5) (2) (7, $8) (3)($9.5) (4) (5, $6.5)

You are a manager in charge of monitoring cash flow at a major publisher. Paper books comprise 80 percent of your revenues, which grow about 2 percent annually. You recently received a preliminary report that suggests the growth rate in ebook reading has leveled off, and that the cross-price elasticity of demand between paper books and ebooks is −0.2. In 2019, your company earned about $150 million from sales of ebooks and about $600 million from sales of paper books.    If your data analytics team estimates the own price elasticity of demand for paper books is −2.5, how will a 1 percent decrease in the price of paper books affect your overall revenues from both paper books and ebooks sales?

Suppose that the demand curve for a product is given by = 100 – 2 Px+a Py, = £20 is the price of another product, and where a Py %3D where Px = £20, where = 8. a) Calculate the demand for good X in this market at the current price level. How much revenue would the firm make? b) If the firm wishes to increase total revenue, would it need to increase or decrease the current price of good X? c) Calculate the cross-price point elasticity between goods X and Y at the current price level. Are the goods complements or substitutes? Note: The writing is clear and abbreviations are not allowed.

Suppose it is known that the number of goods "X" demanded and offered at two different price levels is as shown in the following table: Price Amount Requested (Unit) Amount Offered (Unit) (IDR) 120 160 180 150 2400 2000 Based on the data in the table above, determine the demand function (Qd) and the supply function (Qs) of the goods "X", and determine the market equilibrium point and draw a graph of the market balance!
