At clement's jr. high school, a student needs an 86 average to earn a b. sue's average on
the first four tests in earth science so far is an 84. whạt grade must she earn on the last test to
achieve a b average -

Sue must score 94 on the final test to earn a B.

Step-by-step explanation:

There are five tests in total.

Sue's average on the first four tests is 84.

If after the final test, she scores X, she will have a B on average of five tests.

We have the following equation:

86 = (4 × 84 + X)/5

<=> X = 5 × 86 - 4 × 84

=> X =  94
