Question

Barney averages 88% through four tests. What does he need on the fifth test to raise his average to 90%

Answer 1

To raise his average to 90%, Barney needs to score 98 on the fifth test.

Step-by-step explanation:

In order to calculate the score that Barney needs on the fifth test to raise his average to 90%, we can use the following equation:

(Total Score/Total Number of Tests) = Average

Since Barney has taken four tests and averages 88%, his total score is 4 * 88 = 352. To find the score he needs on the fifth test, we can rearrange the equation:

(352 + Fifth Test Score)/5 = 90

Solving for the Fifth Test Score, we get:

Fifth Test Score = 450 - 352 = 98

Answer 2

98 is the correct answer
