Iman collects quarters,dimes, nickels, and pennies. This morning he took $1.80 from his collection . He counted the coins and found that he had twice as many nickels as dimes . What coins iman have?

Half of 1.80 is 0.90
Take it from there. 
There must be some missing info
various solutions are possible
q d n p
1 1 2 125
2 4 8 50
4 3 6 20
6 1 2 0
and lots of others 
Hmm. I see what Ms Sue is saying. If there are only nickels and dimes, then each makes up half the total.
