Final answer:
To determine the cost per ounce of guaifenesin syrup, divide the total cost, $46.16, by the total quantity, 32 ounces, yielding $1.4425 per ounce.
Step-by-step explanation:
To find out how much the guaifenesin syrup costs per ounce, you simply need to divide the total cost by the total number of ounces. The pharmacy pays $46.16 for 32 ounces of syrup.
