The inverse demand function for grapes is described by the equation p=518 - 5q, where p is the price in dollars per crate and q is the number of crates of grapes demanded per week. When p $40 per crate, what is the price elasticity of demand for grapes? %3D %3D

It is known that the daily demand for theater plays is a function of ticket prices in the form Q = a-bP. While 400 seats were filled every day, the plays were played free of charge on March 27, World Theater Day, and a total of 1200 seats were filled. So what is the price elasticity of demand?

Suppose the demand function for a firm's product is given by In Qxd = 7 -1.5 In Px + 2 In Py-0.5 In M + In A where: Px = $15 Py = $6 M = $40,000, and A = $350 a. Determine the own price elasticity of demand, and state whether demand is elastic, inelastic, or unitary elastic. Own price elasticity: Demand is: (Click to select) b. Determine the cross-price elasticity of demand between good X and good Y, and state whether these two goods are substitutes or complements. Cross-price elasticity: These two goods are: (Click to select) c. Determine the income elasticity of demand, and state whether good X is a normal or inferior good. Income elasticity: Good X is: (Click to select) d. Determine the own advertising elasticity of demand.

The demand function for a certain make of ink-jet cartridge is the following where p is the unit price in dollars and x is the quantity demanded each week, measured in units of a thousand. p= -0.02x² -0.2x+6 Compute the elasticity of demand when x = 11. (Round your answer to two decimal places.) 0.22 Determine whether the demand is inelastic, unitary, or elastic when x = 11. elastic inelastic O unitary
