The hospital shop buys cereal bars in pack of 4. In one day they sell 58 cereal bars. How many packs of cereal bars did they use that day?

So the question is if a hospital shop buys cereal bars in packs of 4 and they sell 58 cereal bars, how many packs did they sell. So we need the number of packs that can contain 58 cereal bars. Since the closest number of packs that can contain 58 bars is 15 because 15*4=60, The answer is they used 15 packs and 2 bars remained because they sold 58 of 60 bars of cereal.
