Wow I am so glad I found this forum and all you math wiz'

Thanks :)

Since you have 8.50 worth of coins rather than 8.50 coins, you need to multiply the number you have of each coin by the worth of that coin in the first equation.


The others look ok, except that there is a typo in the 3rd one; you have d in there twice an no n. Also, you have not included enough brackets for the equation to be technically correct.

Thanks so much!
