    3 quarters and 7 pennies

    Step-by-step explanation:

    You can write equations, but you can also use the trial and error method.

    Guess 1:

    1 quarter = 25 cents

    82 - 25 = 57

    57 pennies = 57 cents

    25 cents + 57 cents = 82 cents

    57 - 1 = 56

    He has 56 more pennies than quarters, so this is not the answer.

    Guess 2:

    2 quarters = 50 cents

    82 - 50 = 32

    32 pennies = 32 cents

    50 cents + 32 cents = 82 cents

    32 - 2 = 30

    He has 30 more pennies than quarters, so this is not the answer.

    Guess 2:

    3 quarters = 75 cents

    82 - 75 = 7

    7 pennies = 7 cents

    75 cents + 7 cents = 82 cents

    7 - 3 = 4

    He has 4 more pennies than quarters, so this is the answer.

    Answer: 3 quarters and 7 pennies
