    Answer: There were 89 retail stores in 1997.

    Step-by-step explanation:

    Hi, to answer this question, first, we have to calculate the number of years since 1990 (x).

    1997-1990 = 7 years

    Now, we simply substitute x=7 (years) in the equation given

    y=11x+12

    y=11 (7) + 12

    y=77+12

    y = 89 retail stores

    There were 89 retail stores in 1997.
