The information we have is:
5 drops of flavor are needed for 12 ounces of water.
To solve the problem, first we need to find the amount of drops needed per ounce of water, and then multiply that by the number of ounces that we need which is 1280.
The number of drops per ounce:
To find this, divide 5 drops by 12 ounces:
5/12 drops are needed per ounce.
The number of drops in 1280 ounces:
Now we multiply 5/12 by 1280:
And the result is:
The number of drops needed is: 533.333
Answer: 533.333 Drops
