emily has earned the following grades A, c+, a-, b - and b+. what grade must she earn in her biology class to keep her 3.2 gpa?

B+

Step-by-step explanation:

Grades earned in five subjects are;

A, C+, A-, B - and B+

Remaining subject is biology

Total number of subjects will be=6

3.2 gpa as a percentile = 86

For her to maintain 3.2 gpa total sum of percentile in the 6 subjects should be at least

6*86=516

Emily total sum of subjects in percentile is 93+77+90+80+87=427

Find the difference, 516-427=89

89 is grade B+

Emily should earn a grade of B + to keep her 3.2 gpa
