13.8900 this is the answer. it is like this because thousandth is.0000. it Cant be 13.0089 because you would change the number.
Just plot it and solve by counting
Since it is 4 times as many quarters and dimes, you can use a chart for guess and check. I started with 8 dimes and 32 quarters.
If you keep going, you end up with the fact that there are 36 quarters and 9 dimes.
