Ella has 164 ounces of lemonade. She fills glasses with 8 ounces of lemonade each until all the lemonade is gone.
The last glass is not full. How much lemonade is in the
last glass?

4 ounces

Step-by-step explanation:

We're looking for the remainder of ounces.

To find how many FULL glasses will be made, we divide 8 by 164 and look at the integer part of the number.

So 2 full glasses were made.

To find the remainder, we multiply 20 by 8 and subtract from 164.

Hope this helped!

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
