Janet has three times as many dimes as nickels and twice as many quarters as nickels. If she has $3.40 in all, how many nickels, dimes, and quarters does she have?
I Got 5n+30n+50n=340
Is This correct?

$$ Let \ \ \ Nickels   = n   \  Quarters  =2n \ Dimes  =  3n \   50n + 30n + n = 340 \  85n = 340 \  n = 4 \\  So \   Nickels   \  =  4   \  Quarters  \ = \ 2n  =  8   \  Dimes  = \ 3n =  12  $$
