he quantity demanded each month of Russo Espresso Makers is 250 when the unit price is $136. The quantity demanded ach month is 1000 when the unit price is $106. The suppliers will market 750 espresso makers when the unit price is $80 er higher. At a unit price of $100, they are willing to market 2250 units. Both the supply and demand equations are known o be linear. (a) Find the demand equation. -1 -x + 146 25 p = (b) Find the supply equation. 1 x+ 70 p = 75* (c) Find the equilibrium quantity and the equilibrium price. |× units

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
