    Step-by-step explanation:

    if you add 100,000 people + 2,000 babies were born and also have to subtract – 3,000 people = you got 99,000 +  10,000 = 109,000 round the number to 108,000

    Answer:

    108,000

    Step-by-step explanation:

    1) 1000 people died

    100,000 – 1000 = 99,000

    2) 2000 babies were born

    99,000 + 2,000 = 101,000

    3) 3000 people moved out

    101,000 – 3,000 = 98,000

    4) 10,000 people moved in

    98,000 + 10,000 = 108,000
