Answer: You are correct. The answer is choice (H) 4.84
======================================================
Explanation:
10% = 10/100 = 0.1
10% of 4.4 = 0.1*4.4 = 0.44
Increasing 4.4 by 10% means we add on 0.44 to get 4.4+0.44 = 4.84
So the ruler says 4.4 inches but the actual table could be as long as 4.84 inches.
---------
A shortcut is to compute it like this:
4.4*1.1 = 4.84
The multiplier 1.1 represents an increase of 10% because
1.1 = 1 + 0.1 = 100% + 10%
This shortcut allows for multiple percentage increases that can be chained together fairly quickly.
