a. Estimate the PE ratio for Cracker Barrel.
b. Estimate how much higher the PE ratio would have been if it had been able to maintain the growth rate in earnings that it had posted between 1983 and
1993. (Assume that the dividend payout ratios are unaffected.)
c. Now assume that disappointing earnings reports in the near future lower the expected growth rate between 1994 and 1998 to 10%. Estimate the PE ratio.
(Again, assume that the dividend payout ratio is unaffected.)
