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.
