Scores are 78,81,83, and 76 what must she earn on the fifth test to earn an average test score of 81
iogann1982 [59]
The average value of a data set is equal to the sum of each entry divided by the number of entries. In this case, we have 5 scores, so we can find set up the following equation where x is the fifth score:

\dfrac{78+81+83+76+x}{5} = 81

Now solve for x:

78 + 81 + 83 + 76 + x = 81(5)

318 + x = 405

x = 87

The fifth score must be 87.
