Answer: B) 12.5

Explanation:

Start by isolating x by subtracting 2.5 from both sides


x+2.5 < 20\\x+2.5-2.5 < 20-2.5\\x < 17.5

This reads as "x is less than 17.5"

D can be eliminated because it is greater than 17.5

C can be eliminated because 17.5 can't be less than itself

So the answer must be B since it is less than 17.5 and greater than A
