Answer:
112 tiles
Step-by-step explanation:
Area = 28ft sq
Tiles are 1/4 each sqft
We are working cube square inside cube ft square = 1 sq /4 (for multiplier).
= 4 x 28 = 112
112 x 0.25 = 28 to check.
112 x 0.25 x 4 = 112 is the multiplier to check again.

The mean of n numbers is the sum of the numbers divided by n.
You have a mean score of 84 after taking 5 tests. Let x be the sum of scores.

You scored a total of 420 points on five tests.
You need to have a mean score of 85 after taking 6 tests. Let y be the score you need to obtain. Your total score on 6 tests is 420+y.

You need to score 90 points on the sixth test.
