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.
