8 Over the years voting have been changed and re arranged. First only whitemales with money could vote then, white males then white women then all races.Different groups had to fight for their ability to vote which to years even decades tocome across. I feel this was unnecessary to have it discriminated that way, but youcan't change the past. This broadens the voter turnout by allowing more citizens to beable to vote Now we are able to hear different opinions and ideas on how the economyshould be ran.

Answer 2

To get an average score of 80% (out of four exams), a total of 4*80%=320% is needed, so the minimum required for the 4th test is 320-(75+97+60)=88.
To get an average score of 89% (out of four exams), a total of 4*89%=356% is needed, so the maximum required for the 4th test is 356-(75+97+60)=124, which is impossible.
So the next exam grade must range between 88 and 100 to get a grade b in the class.
