  1. 1

    Step-by-step explanation:

    t,total amount of sale = price,p x sales,s =

    t=p*s

    price increased by 10% p 1 = px(1+10%)=p(1+0.1) = 1.1p =

    sales decreased by 10% s1= sx(1-10%) = s(1-0.1) = 0.9s

    t1 = s1 * p1

    = 1.1p * 0.9 s =0.99ps =0.99t =

    creased from t to t1

    = t1-t/t x100

    =0.99t -t/t x100
