Question

to determine a student's grade, a teacher throws out the lowest grade obtained on 5 tests, averages the remaining grades, and round up to the nearest interger. If Betty scored 75,90,88,72,and86 on her tests, what grade will she receive​

Answer 1

B grade

Explanation:

75 + 90 + 88 + 86 = 339

339/4 = 84.75

Grade B = 80-89%

Answer 2

Betty will get 85 grade.

Explanation:

Betty scored 75,90,88,72, and 86 on her tests.

As given the teacher throws out the lowest grade, we will not consider 72.

Now the teacher averages the remaining grades, and round up to the nearest integer.

So, taking the average we get;

`(75+90+88+86)/(4)`

= 84.75

Rounding this to nearest integer, we get 85.

Hence, Betty will get 85 grade.
