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.
