arctic games held every 2 years. in 1970 it had 700 competitors in 2000 it had 2000. determine the ANNUAL growth rate. Helpppppppp!

  1. Damon

    2000 = 700 x^(2000-1970)

    2.857 = x^30

    log 2.857 = 30 log x

    log x = .0151977

    x = 1.0356
    so
    3.56 percent per year

  2. Damon

    check
    700 * 1.0356^30 = 1999.99
