Question 1133991
Sue has eight times more nickels as she has dimes in her piggy bank. She has $2.50 in her piggy bank. How much of each type of coin does she have?

------------
n = 9d
5n + 10d = 250
---------
5*9d + 10d = 250
55d = 250
No integer solution, and you can't have a fraction of a coin.
===========================
PS  8 times more is not the same as 8 times as many.
1 time more = 2 times as many, right?
100% more is 2x as much, right?
