Valerie's right. If you think about it, by your logic of "20-ten cents" for two dollars, then the answer for one dollar would be TEN-ten cents, not just ONE-ten cents.

So while you're correct that one dime equals 1-ten cents (and that's a good way to count it when showing the value of a dime), the question isn't how many CENTS are in 2 dollars, but how many DIMES. 20 dimes, which in 'math language' is 2-10 dimes.

Hello Venla,

After looking into this and speaking with you. I will advise to have the words 2-ten dimes added in the text.

Thank you for bringing this to our attention!
