    Step-by-step explanation:

    The worth of a dime is 10 cents. Converting to dollars, it becomes

    10/100 = $0.1

    8 dimes = 8 * 0.1 = $0.8

    The worth of a penny is 1 cent. Converting to dollars, it becomes

    1/100 = $0.01

    10 pennies = 10 * 0.01 = $0.1

    The worth of a nickel is 5 cent. Converting to dollars, it becomes

    5/100 = $0.05

    25 nickels = 25 * 0.05 = $1.25

    The worth of a quarter is 25 cent. Converting to dollars, it becomes

    25/100 = $0.25

    12 quarters = 12 * 0.25 = $3

    16 half dollars = 16 * 0.5 = $8

    14 one-dollar = 14 * 1 = $14

    The total amount of money that he has is

    14 + 8 + 3 + 1.25 + 0.1 + 0.8 = $27.15

    Since he wants to buy a $30 computer game, then the additional amount that he needs to borrow from her dad is

    30 - 27.15 = $ 2.85
