is an inferior good with an income elasticity of -1 and soy-burgers are normal goods with an income elasticity of 1.

Explanation:

The options to this question wasn't provided. Here are the options:

and soy-burgers are both normal goods with income elasticities equal to 1.

is an inferior good with an income elasticity of -1 and soy-burgers are normal goods with an income elasticity of 1.

is an inferior good and soy-burgers are normal goods; both have income elasticities of 1.

and soy-burgers are both inferior goods with income elasticities equal to -1.

An inferior good is a good whose demand increases when income falls and whose demand falls when income rises.

Inferior goods have an inverse relationship with income.

From the question, we can see that Heathers demand for macaroni fell when her income increased, so macaroni is am inferior good.

A normal good is a good whose demand increases when income increases and falls when income falls.

A normal good has a direct relationship with income

From the question, we can see that Heathers demand for soybeans fell when her income increased, so soybeans is a normal good.

Income elasticity of demand measures the responsiveness of quantity demanded to changes in income.

Income elasticity of demand = percentage change in quantity demanded / percentage change in income

Percentage change in quantity demanded for macaroni = (10-5) / 10 = 0.5 × 100 = 50%

Percentage change in quantity demanded for soybeans = (4-2)/2 = 1 × 100 = 100%

Percentage change in income = ($20,000 - $10,000) / $10,000 = 1 × 100 = 100%

Income elasticity of demand for macaroni = 50% / 100% = 0.5

Income elasticity of demand for soybeans = 100% / 100% = 1

Macaroni had an inelastic demand because it's coefficient of elasticity is less than one.

Soybeans has an elasticity equal to one because its coefficient of elasticity is equal to one.

Annuity payments are assumed to come at the end of each payment period (termed an ordinary annuity). however, an exception occurs when the annuity payments come at the beginning of each period (termed an annuity due). what is the future value of a 13-year annuity of $2,800 per period where payments come at the beginning of each period? the interest rate is 9 percent. use appendix c for an approximate answer, but calculate your final answer using the formula and financial calculator methods. to find the future value of an annuity due when using the appendix tables, add 1 to n and subtract 1 from the tabular value. for example, to find the future value of a $100 payment at the beginning of each period for five periods at 10 percent, go to appendix c for n = 6 and i = 10 percent. look up the value of 7.716 and subtract 1 from it for an answer of 6.716 or $671.60 ($100 × 6.716)

Onsider the following subscription behavior information from genie, a web site that provides tools for constructing a family tree (ancestor search). subscriptions cost $9.99 per month, but you are charged for the entire year at the time of purchase. there is a one-year minimum term when you sign up for the service. once purchased, subscriptions are set to renew automatically unless the subscriber cancels them. when a membership renews, it renews for a one-year term and again you are charged for the entire year. there are no variable costs associated with providing this service to an individual customer, but genie does engage in customer relationship activities that they believe will increase customer retention. these customer relationship activities cost genie about $10 per year per customer. based on a sample of 1000 customers that joined genie five years ago, near the time when the company was founded, they were able to determine how many of those customers remained subscribers in the second year, third year etc. based on this information, genie calculated the average annual retention rate to be 20%. genie uses an annual discount rate of 8%. a. last year, genie spent $10,000 placing advertisements on google. genie management believes that these advertisements were responsible for about 300 new subscribers. would you recommend to genie management that they purchase more google ads? b. suppose a newly-introduced loyalty program increases the number of customers that remained to 30%. does this new data change your answer to 9.a? c. do you have any hesitations or concerns about making recommendations to management based on your above estimate of customer lifetime value?
