Adrink dispenser fills cups at a rate of 2 ounces per second. adrain has 64 ounce cup that already contains 18 ounces of water. how long will it take the dispenser to fill the rest of his cup with water

23 seconds

Step-by-step explanation:

First, find out how many ounces left are needed to fill the water. Subtract the total, 64, by the already filled, 18. This should get you the answer of 46.

Since the dispenser fills 2 ounces per second, you need to divide the number 46 by 2 in order to find the amount of time in seconds it would take to fill the rest of the cup.

Therefore, your answer is 23 seconds.

Hope this helps!
