Answer:

X \leq 3Y

And we can rewrite this expression like this, subtracting 3Y from both sides of the last inequality:

X-3Y \leq 3Y-3Y

And we got:

X -3Y \leq 0

And for this case the best answer would be:

b. X - 3Y≤ 0

Explanation:

For this case we need the following condition: "the quantity of X must be at most three times as large as the quantity of Y."

And we can convert this into a mathematical formula like this:

X \leq 3Y

And we can rewrite this expression like this, subtracting 3Y from both sides of the last inequality:

X-3Y \leq 3Y-3Y

And we got:

X -3Y \leq 0

And for this case the best answer would be:

b. X - 3Y≤ 0
