29. Suppose that 50 candy bars are demanded at a particular price. If the price of candy bars rises by 4 percent, the number of candy bars demanded falls to 46 candy bars. According to the midpoint method, what does this mean? a. The demand for candy bars in this price range is elastic. b. The demand for candy bars in this price range is inelastic. C. The price elasticity of demand for candy bars is 0. d. The demand for candy bars is unit elastic.

4)Zeke likes to go to music concerts. The number of times per year that he attends concerts depends on both the price of the concerts as well as Zekeâs income and the cost of other types of entertainmentâin particular, how much it costs to go see a movie instead of attending concerts. The three demand schedules in the $60,000 per year and movies cost $10 each. In scenario D2, Zeke's income is also $60,000 per year, but the price of seeing a movie rises to $12. And in scenario D3, Zeke's income goes up to $80,000 per year, while movies cost $12.
a)Using the data under D1 and D2, calculate the cross-elasticity of Zeke's demand for concerts at all three prices. (To do this, apply the midpoints approach to the cross-elasticity of demand.) Is the cross-elasticity the same at all three prices? Are movies and concerts substitute goods, complementary goods, or independent goods?
b)Using the data under D2 and D3, calculate the income elasticity of Zeke's demand for concerts at all three prices. (To do this, apply the midpoints approach to the income elasticity of demand.) Is the income elasticity the same at all three prices? Are concerts an inferior good?
| PRICE | D1 | D2 | D3 |
| 50 | 10 | 5 | 12 |
| 40 | 15 | 10 | 25 |
| 30 | 25 | 15 | 40 |
Income 60,000 60,000 80,000
Cost of revenue 10 12 12

The table below contains information on three techniques for producing $15 worth of bar soap. Assume â$17.50 worth of bar soapâ means the selling price of soap is $3.50 per bar and all three techniques produce 5 bars of soap ($17.50 = $3.50 per bar à 5 bars). So you know each technique produces 5 bars of soap
