1) If the quantity demanded of one good increases from 200 to 300 when the price of another good increases from $5 to $7, what is the Cross-Price Elasticity of Demand?
a: -.4
b: 1.21
c: -1.21
D: .33
2) If the quantity demanded decreases from 480 to 460 when the price increases from $2 to $2.10, the price elasticity of demand in absolute value is:
A: .88, B: 4.3 C: 1.14 D: 1.49
Based on your answer above, demand for the good is ( Elastic or inelastic)
Based on your answer above, the slope of the demand curve will be (flat or steep)
Based on your answer above, when the price increases total revenue will (Decrease or increase)
1.
Cross price elasticity = (Q2-Q1)/(P2-P1) X (P1/Q1)
Cross price elasticity = (100/2) x (5/200)
Cross price elasticity = 1.25
Thus, correct option: (b) 1.21 (approximately)
2.
Elasticity = (-20/0.1) x (2/480)
Elasticity = -0.833 or 0.83 in absolute terms
Thus, correct option: (a) 0.88 (approximately)
3.
Demand for the good is inelastic
The slope of demand curve is steep
When the price increases, total revenue will increase

1)Explain what it means when demand is inelastic? 2) If demand is elastic, total revenue will increase when the price decreases? True or False? 3) The price elasticity of supply will be a smaller number when it is relatively easy for sellers to increase their supply. ( True or False)? 4) Demand is more elastic when the absolute value of the price elasticity of demand is larger. ( True or False)? 5) If the quantity demanded of one good increases...
Suppose that when the price for Good A increases by 7 percent, the quantity demanded for that product decreases by 6 percent. Accordingly, calculate the own price elasticity of demand for Good A. Is demand for Good A elastic, inelastic, or unit elastic?
12. If the price decreases from $10 to $8 and the quantity demanded increases from 50 units to 55 units the price-elasticity of demand at $10 is _______________________. Thus the price elasticity of demand is _______________________ and therefore total revenue can be increased by ________________________ the price. 13. The elasticity of demand gives the _______________ change in quantity demanded give the __________________ change in price. 14. If Demand is relatively elastic and Supply is also relatively elastic and the government...
quantity demanded increases by 60% when price decreases by 40%, we can conclude that the good is: Select one: 0 a, inelastic O b. elastic Oc. normal O d. inferion Next pag swers Jump to...
answer it Immediately please?? it) When the price of a good decreased by 10%, the quantity demanded increased by 30%. (Note: this question is not related to parti). a. Is the demand for this good elastic, unit elastic, or inelastic? Show calculations. b. Are substitutes for this good easy to find or does it have poor substitutes? Is it more likely to be a luxury or necessity? Explain. c. Based on the elasticity explain how total revenue has changed.
13. If the quantity of a good sold varies greatly from small changes in the price, we say that good is: A) highly inelastic. B) unitary elastic. C) not elastic. D) highly elastic. 14. A product's price changes from $2 to $6 and its quantity demanded changes from 10 to 4 units. This is an example of price: A) inelastic demand. B) elastic demand. C) unitarily elastic demand. D) inelastic supply. 13. Which of the following is a possible measurement...
15. When price = $12, quantity demanded = 1,200. When price = $14, quantity demanded = 1,025. When the firm lowered price from $14 to $12, it discovered that demand is_ _ _and total revenue __by a. elastic; increased; $14,400 b. elastic; decreased; $14,400 c. inelastic; increased; $50 d. elastic; increased; $50 e. inelastic; decreased; $3,150
9.When price increase from $43 to $49, quantity supplied increases from 220 units to 240 units. The price elasticity of supply in this price range is (use the Midpoint Formula): Multiple Choice a.0.3 b.0.67 c.1.5 d.3.33 10. When any change in price results in an infinite change in quantity demanded: Multiple Choice a.price elasticity of supply is zero. b.demand is perfectly elastic. c.demand is perfectly inelastic. d.price elasticity of supply is infinite. 12. Over a longer period of time: Multiple...
If the quantity demanded of juice decreased by 15% when the price of juice increased by 10%, the price elasticity of demand for juice is , and the demand for juice is said to be 2/3: elastic c. 3/2; elastic b. 2/3: inelastic d. 3/2; inelastic If the absolute value of the price elasticity of demand for milk is equal to 0.6, the demand for milk is: a relatively elastic. C. relatively inelastic, b. unit elastic. d. perfectly inelastic, demand...
The price of widgets is $20 and the quantity demanded at $20 is 100. The price of widgets decreases to $10 and the quantity demanded increases to 120. Calculate the price elasticity of demand, being sure to show enough work that it is clear to follow your process. Is this elastic or inelastic? What should be done, if anything, to price to increase revenues?
