How did high tariffs and low taxes boost the economy during the 1920s?

 A tariff is imposed on products approaching into a country. It is completed to guard industry from foreign goods being inexpensive than homebased products. Taxes are money that individuals pay to sustain the government. For the duration of inflation (bags of money in the economy) the government must tax more to give sense to the money. When there’s a recession, or little money, the government can't tax as much because the individuals don't have adequate to give, therefore boosting economy.

the correct answer is:   "   3.6 % " .

          →   the unemployment rate is:   " 3.6 % " .

explanation:

to calculate the "unemployment rate" :

the "unemployment rate"   =

  [# of people unemployed] /   [working age population]   * 100 %   ;

                =   [9 million] / [250 million]     *   100 % ;

    →     note:   the units of "million" cancel out;

                    since:   " {million} / {million} = 1 " ;

                =   (9 / 250)   * 100 %   ;

                = 0.036 * 100 % ;

                =   3.6 %

answer:   the unemployment rate is:   " 3.6 % " .
