ONE WAY TO DO IT:

writing as
and subtracting

It is what you would do if you had $ and had to pay $ with exact change.
You would ask for change for $1, and get two $ ($0.50) coins in its place.
You would have $13 in bills that you would use to pay the $1 part of $ ,
keeping the other $13-$1=$12 in bills,
and you would use 1 of the 2 $ coins to pay the rest of the $ ,
keeping the other $ coin
That would leave $12 in bills and $ in coin in your wallet.
