latrell wants to keep his test average in his class at 85 or higher. so far, he has earned score of 85, 76, 94 and 81 on his tes
Lena [83]

Answer:

89

Step-by-step explanation:

Use the mean formula, mean = sum of elements / number of elements.

He wants to keep his average at 85 or higher, so plug in 85 as the mean. Let x represent the score he has to get, and solve for x:

mean = sum of elements / number of elements.

85 = (85 + 76 + 94 + 81 + x) / 5

85 = (336 + x) / 5

425 = 336 + x

89 = x

So, he has to get a 89.
