Explain ONE economic cause of the growth of the Atlantic slave trade.

Here you go!

Explanation:

The Atlantic slave trade began because the (Encomienda system), a system of forced labor between (peninsulares) and (mestizos as well as native Americans), ended since it was seen as cruel to the native laborers. Europeans in the Americas wanted to reduce the strain on natives by bringing in Africans to work.

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 % " .
