Answer:

81

Step-by-step explanation:

Given total number of tests are 5

The grades earned by the students in the tests are 84 , 75 , 97 , 89

let the grade earned by the student in the fifth test be x.

Average=\frac{84+75+97+89+x}{5}

The condition recquired is Average≥85

\frac{84+75+97+89+x}{5}≥85

\frac{344+x}{5}≥85

x+344≥425

x≥81.

The least grade the student can earn in the last test so that average is not less than 85 is 81
