The following data represent the mean prices per pound of fresh tomatoes from 1980 through 1989. Complete parts (a) through (e). a. Calculate the simple price indexes for 1980 through 1989, using 1980 as the base year. Year Price Year | Price Price Index (Base = 1980) 1980 0.764 1980 0.764 100 1981 0.713 1981 0.713 93.32 1982 0.715 0.874 1982 0.715 93.59 1983 1984 0.868 1983 0.874 114.40 1985 1.118 1984 0.868 113.61 1986 0.999 1987 0.984 985 1.118 146.34 1988 1.086 1986 0.999 130.76 1989 1.186 1987 0.984 128.80 1988 1.086 142.15 1989 1.186 155.24 (Round to two decimal places as needed.) b. Interpret the simple price index for 1989, using 1980 as the base year. The average price per pound for tomatoes is 55.24 % higher in 1989 than it was in 1980. c. Recalculate the simple price indexes found in (a) using the equation below, with 1985 as the base year. old new =
