    The answer is option (A), about 40 and one half pounds

    Step-by-step explanation:

    Step 1: Determine the initial weight of the dog

    Initial weight of dog=42 8/9 pounds

    Step 2: Calculate weight after gain

    Weight after gain=Initial weight+additional weight gain

    where;

    Initial weight=42 8/9 pounds

    Additional weight gain=3 1/2 pounds

    replacing;

    Weight after gain = (3 1/2) + (42 8/9) = 7/2+386/9=46 7/18

    Weight after gain=46 7/18 pounds

    Step 3: Calculate weight after you put him on a diet

    Weight after diet=Weight after gain-weight lost after diet

    where;

    Weight after gain=46 7/18 pounds

    Weight lost after diet=6 7/16 pounds

    replacing;

    Weight after diet = (46 7/18) - (6 7/16) = (835/18) - (103/16) = 39 137/144 pounds

    Weight after diet = About 40 and one half pounds
