The demand function for good X is ln Qdx= a + b ln Px + c ln M + e, where Px is the price of good X and M is income. Least squares regression reveals that â = 7.42, b ˆ = −2.18, and ĉ = 0.34. a. If M = 55,000 and Px = 4.39, compute the own price elasticity of demand based on these estimates. Determine whether demand is elastic or inelastic. b. If M = 55,000 and Px = 4.39, compute the income elasticity of demand based on these estimates. Determine whether X is a normal or inferior good.

HINT: Find price elasticity of demand by multiplying the slope of the regression line from Excel by the mean real price then divide by the mean quantity demanded.A charity is considering operating a lemonade venture for the summer. The assumption is that they can sell up to 9,000 units of lemonade at a price of $3.00. In addition, it is assumed that if lemonade is sold for $4.00 that sales would decline to 6,500 units. Consider a simple demand curve for the lemonade venture. To develop a demand curve from these estimates, it is assumed that the relationship between price and quantity is linear, meaning that the change in quantity will be proportional to the change in price. Graphically, you can infer this relationship by plotting the two price-quantity pairs on a graph and connecting them with a straight line. Using intermediate algebra, you can derive an equation for the linear demand curve P=6.6-(-0.0004Q) Please assist me to plot he graphs for the scenarios above. I don't know what to do.
