notka56 [123]

Question:

A grocery store has 120 bottles of spring water in stock.  The store orders bottles of spring water in cases of 24.  The store wants to order enough cases of spring water so it has more than 500 bottles in stock.  Which inequality best models this situation?

A.  24x + 120 > 500

B.  24x - 120 > 500

C.  24x + 500 > 120

D.  24(x+120) > 500

Answer:

Option  A.  24x + 120 > 500  is the inequality that best models this situation.

So there are already 120 bottles in stock .

The store will order

24x +120  > 500

where x  is the number of spring water bottle cases
