Olivia is brewing tea. She starts boiling 0.455 L of water in a kettle. The change in volume of the contents of the kettle are noted below. First, Olivia adds tea leaves. This increases the volume of the contents by 0.056 L. After a few minutes of brewing, evaporation brings the volume down by 0.004 L. Finally, Olivia pours herself a cup, which reduces the volume of the contents of the kettle by 0.168 L. What is the volume of the contents of the kettle after Olivia pours herself a cup of tea?

    Answer:

    C (0.339 L)

    Step-by-step explanation:

    Volume after adding tea leaves = 0.455 + 0.056 = 0.511 L

    Volume after evaporation = 0.511 – 0.004 = 0.507 L

    Volume after pouring out a cup = 0.507 – 0.168 = 0.339 L    [Ans]

    Hope this helps!
