the school store has1200 pendls in stock and sells and sells an average of 25 pencils per day the manager reorders when the numb
forsale [732]

Answer:

Number of pencils in stock = 1200

Average number of pencils sold by the manager per day = 24

Number of pencils that would be sold before reordering = 1200 - 500

                                                                                        = 700

Then

The number of days after which the manager will reorder = 700/24

                                                                                            = 29.16

So the manager has to reorder after about 30 days. Since the answer comes in fraction of more than 29 days, so it has to be 30 days. I hope the procedure is clear for your understanding.

Just to be clear, this answer is not mine, but I remember seeing this question so I just copied someones' answer. Still, you might find this helpful.
