    Answer:

    • 15 dimes
    • 10 quarters

    Step-by-step explanation:

    Let q represent the number of quarters. Then Tony’s coin value is …

      0.25q +0.10(25 -q) = 4.00

      0.15q +2.50 = 4.00 . . . . . . . . eliminate parentheses, collect terms

      0.15q = 1.50 . . . . . . . . . . . . . . subtract 2.50

      q = 10 . . . . . . . . . . . . . . . . . . . . divide by the coefficient of q

    Then the number of dimes is …

      25 -10 = 15

    Tony has 15 dimes and 10 quarters.
