Instruction :
Let's imagine I create a fake currency called Yarns with two types of coins: a super-yarn (worth 10 yarns) and a mini-yarn (worth 0.5 yarn). How much money do I have in total if I have 2 super-yarns and three mini-yarns?

Response:
Given that a super-yarn is worth 10 yarns and a mini-yarn is worth 0.5 yarn, if you have 2 super-yarns and 3 mini-yarns you have 21.5 yarns in total.
