I think I can bravely ignore the Freudian slip and solve this one.
-- If the mean of 5 tests is 90, then all 5 scores add up to (5 x 90) = 450
-- The sum of her first 4 scores is (95+ 90 + 85 + 95) = 365
-- If she has one more test to average 90, then she needs
to score (450 - 365) = <u>85</u> on it.
That looks like choice 'G '.
No, because 40 x 10 is not 4000, but is is 400. It is 100x greater not 10x
The answer would be no. She needs 264 plastic covers in order to fit all comic books.
Divide 1,056 by 4
You should get 264. <span />
