Final answer:
Five bottles of glipizide should be ordered to reach the maximum quantity, as the calculation is 11 bottles (maximum) minus 6 bottles (current stock). This answer is not present in the provided choices, indicating a possible error in the options.
Step-by-step explanation:
The question at hand involves calculating how many more bottles of glipizide need to be ordered to reach the maximum quantity. The stock currently has six bottles, the par level is five bottles, and the maximum quantity that can be held is 11 bottles. To find out how many more bottles should be ordered, subtract the number of bottles currently in stock from the maximum quantity desired:
Maximum quantity - Current stock = 11 bottles - 6 bottles = 5 bottles
Therefore, five more bottles of glipizide should be ordered to reach the maximum quantity of 11 bottles. The answer is not listed among the choices a)-d), which suggests there may be a mistake in the options provided.
