Answer:

24 days = 1500 tables

25 days = Fewer than 1500 tables

Explanation:

So we have the inequality of < which is fewer than. Let's start by labeling all the numbers given.

What we want to find is how many days, so we'll make days = x

2100 is the initial and they sell 25 a day... 25 a x.

Combining them all we get a basic inequality of:

2100 - 25x < 1500

Let's get X alone.

Subtracting 2100 from both sides gives you

-25x < -600.

We have negatives on both sides. For me, if I see that, I make both of them positive;

25x < 600

Last step is to divide the 25 out of the X which means you'll divide 25 by 600 also

X = 24

Which means day 24 will be exactly 1500. We wanted fewer though, so adding a day gives you an answer of 25 days.
