    Answer:

      900 grams

    Step-by-step explanation:

    The equation tells you the initial amount of A is 700 grams.

    The table tells you B is being cut in half each hour, so the amount when h=0 is 2×800 = 1600 grams.

    The difference in the initial amounts is …

      1600 -700 = 900 . . . grams
