Q: If y is an integer, then the least possible value of [23-5y] is... brackets are supposed to indicate absolute value.

a-1

c-3
d-4
e-5

thanks

Okay, onto your query.
You have answered a question different from the one posed. You've answered the question, "What value of y will yield the least possible value of |23 - 5y|?"

So, when y = 5, |23 - 5y| = |23 - 5(5)| = |-2| = 2 (and 2 is the smallest possible value of |23 - 5y|)

However, the question asks, "What is the least possible value of |23 - 5y|?
So, the least possible value of |23 - 5y| is 2 (and this occurs when y = 5)

Cheers,
