    Growth, rate: 30%

    Step-by-step explanation:

    Since 1.3 > 1,

    It's growth

    (1.3 - 1) * 100

    = 30%

    growth 30%

    Step-by-step explanation:

    This is in the form

    y = a b^x

    Where b is the growth rate

    b>1 it is growth

    b<1 it is decay

    1.3 >1 so it is growth

    b-1 =.3 so the growth rate is. 3 = 30%
