Shawn takes 8 ounces of his medication daily. If the bottle contains 128 ounces, how many days will it last?

To determine how many days the medication will last, you can divide the total amount of medication in the bottle by the daily dosage.

In this case, Shawn has a total of 128 ounces of medication and he consumes 8 ounces each day. Performing the division:

128 ounces ÷ 8 ounces per day = 16 days.

This calculation shows that with a daily intake of 8 ounces, the 128-ounce bottle will last for 16 days. Therefore, the correct answer reflects the result of this division, confirming that the bottle will indeed last for 16 days.
