    32

    Step-by-step explanation:

    "A number decreased by 7" would be (n-7).

    If 4 is mult. by this quantity, the product is 100:

    (n-7) (4) = 100.

    Dividing both sides by 4 clears out the fraction (s) : n - 7 = 25.

    Adding 7 to both sides isolates the desired answer, n:

    n = 25 + 7 = 32
