Answer:
Part A.) 153 Boxes
Part B.) 394 Boxes (395 if rounding up)
Explanation:
The inequality used in this situation would be:
3.74x + 25 < 600
3.74 is the price of each box
x is the number of boxes
25 is that deposit
and < 600 is not making $600 in sales
What we need to do is get X alone. First we will subtract 25 from both sides since that's the opposite of +25.
Doing that will get you
3.74x = 575
Next step is to divide 3.74 on both sides since 3.74 is being multiplied by x and division is the opposite.
That will give you X = 153.74. We round down to stay under and we end up with 153.
For part B, we would do the same process, but instead of < 600, we would do >= 1500. Just typing the same steps out.
3.74x >= 1475 since we subtract 25 from both sides
x = 394.38 since we divide 3.74 on both sides. Rounding would get us 394
