    This cannot be determined. Each store might have had a different retail amount in 1977.

    i believe its R... you multiply the percentages across the 2 years for each store, to get the total percentage change per store. it doesn't matter what the actual $ value is to start with as we're dealing with percentage...

    The data given are %change. We have no information about the absolute quantities, just the relative differences.

    The question is about absolute quantities => Can't be determined.

    Let's say P sold 10.000$ in 1977, we can find the mount sold in 1979 easily:
    10.000*(1+10/100)*(1-10/100)

    An so on eith each one of the companies.

    The problem is we have no initial amount, no 10.000$ or whatever so we can't do any calculatons

    ANSWER is E
