● 1. The table below lists 4 observations of price (Px) and quantity (Qx) for a product X, their respective averages or means, and the estimated Q values (Q*) based on a demand function (Q* = 208-0.1Px). Entry Px Qx Q* 1 $220 176 186 2 $520 147 156 a. Compute the TSS value for the observation above: 3 $480 153 160 b. Compute the SSE value for the observations above: 4 $580 144 150 5 $340 175 174 c. Compute the R² value (round to two decimals) based on your answers above and interpret its meaning: Mean $428 159

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.

What is the current price of gasoline and how many gallons of gasoline do you currently buy per month? How many gallons would you buy next month and how would your behavior change if the price fell by $1.25 per gallon? Also, based on that information, what is your price elasticity of demand for gasoline? Be sure to show how you calculated your price elasticity of demand.     current price of gas = $2.53 gallons of gas per month = 72 gallons no change for next month On the average I fill my tank up 3 times a month each time I go I spend $60-$65

*4* When the price of product "X" is (P1=) $42, Shyanne purchases 20 units of product "X" and when the price of product "X" is (P2=) $38, she purchases 30 units of product "X". Shyanne's "arc" price elasticity of demand for product "X" is (Ex,x =): O" -0.25 " and the demand for "X" is relatively elastic. -4.00 " and the demand for "X" is relatively inelastic. O"-0.25 " and the demand for "X" is relatively inelastic. O " -4.00 " and the demand for "X" is relatively elastic. -0.25 " and "X" is a "normal" good. Save & Continue Continue without saving
