Approximately what real rate of interest could Tyra earn if she invests her money? How many items can she buy at Dollar Barrel today, and how many can she buy a year from now if she invests her money and goes shopping later? What is the percentage increase in Tyra's purchasing power if she waits a year to go shopping? Compare your answer to the approximate real rate of interest on Tyra's investment. b. Now suppose that the expected inflation rate is 10% and Tyra can earn 19% on money that she invests over the year. What is the approximate real rate of interest that Tyra will earn? Calculate the number of items that Tyra could buy next year from Dollar Barrel if she invests her money. What is the percentage increase in her purchasing power if she waits a year to go shopping? Relate your answer back to Tyra's real rate of return The percentage increase in Tyra's purchasing power if she waits a year to go shopping is 4.95%. (Round to two decimal places.) Compare your answer to the approximate real rate of interest on Tyra's investment. (Select the best answer below.) 0 A. The real rate of interest is approximately equal to the nominal rate plus the expected inflation rate O B. The real rate of interest is exactly equal to the difference between the nominal rate and the expected inflation rate ° C.

The real rate of interest is approximately equal to the difference between the nominal rate and the expected inflation rate b. The real rate of interest that Tyra could earn if she invests her money, approximately, is 9 %. (Round to the nearest whole percent.) If she invests her money and goes shopping later, the number of items she can buy is 250. (Enter as a whole number. Do not round up.) The percentage increase in Tyra's purchasing power if she waits a year to go shopping is 870% Round to two decimal places.
