    Since 1 quarter equals 25 cents, 3 will equal 75.

    Then how do you get 85?

    Well 75 + what (x) is 85?

    Or 85 - 75 is what?

    85 - 75 is 10.

    10 cents is a dime. So add a dime to it. So now you have a total of 4 coins. You need to find the leftover 14 coin values.

    So, 10 dimes is a dollar and 4 quarters is a also dollar.

    10 + 4 is 14 and a dollar + a dollar is 2 dollars.

    2 dollars + those 4 coins, 85 cents is $2.85.

    You're final answer is : Martian has 11 dimes and 7 quarters.
