Worldwide annual sales on smart phones over a two year period were approximately q=-5p+3090 million phones at the selling price of $p per phone. (a) obtain a formula for the price elasticity of demand E. E=______ (b) in one of the years the actual selling price was $355 per phone. What was the corresponding price elasticity of demand? E=______ The demand is going (up/down) by about _____% per 1% increase in that price level.

solution plz

If we have a cross-price elasticity of demand of CeD +7.5, which combination of products would best fit with this  value?     (a) Cabbages and cauliflowers (b) iPhone and iPhone charger (c) Washing powder (for clothes) and washing up liquid (for crockery/cutlery) (d) A chicken microwave meal and a vegetarian microwave meal

As a result of increase in the price from 11 to 15 units the quantity demanded decreases by 50% calculate the price elasticity of demand.

4x+200 A garden shop determines the demand function q = D(x) = 30x+9 during early summer for tomato plants where q is the number of plants sold per day when the price is x dollars per plant. (a) Find the elasticity. (b) Find the elasticity when x = 2. (c) At $2 per plant, will a small increase in price cause the total revenue to increase or decrease? (a) The elasticity is

The cross-price elasticity between two products is estimated to be -0.5. If the price of the first product is increased by 8%, demand for the second product will a) increase by 16% b) decrease by 4% c) increase by 4% d) increase by 8%

In the market for cars, the price elasticity of supply is +1.5, and the price elasticity ofdemand is -0.8. The equilibrium price is $ 30 thousand, and quantity is 120 million.(a) Assuming supply and demand are linear, reconstruct and draw the supply and demandcurves. Label the intercepts.(b) To reduce traffic, the government imposes a $400 tax on cars. What are PB and PS after thetax? What is the new equilibrium quantity? Illustrate them on the same graph.(c) How big is the change in consumer surplus, producer surplus, government revenue, anddeadweight loss?
