    1985year ->275cell phones->100%
    1994year -> x cell phones ->100%+360%
    40% • (1994-1985)= 40% • 9= 360%

    275 cell phone 100%
    X cell phones. 100+360%=460%
    x=275•460%/100%
    x=12420/100
    x=1265
    99% sure this is a correct answer

    x=275 • 460%/100%
    x=12,420/100
    x=1265

    1994-1985= 9 yrs • 40%= 360%
