radar · Answer

D=number of dimes
N=number of nickels
Q=number of quarters
N=3+2D
N=3Q-3
5N+25Q+10D=1455

Have I got this right? !!!!

If so there is three equations with 3 unknowns and can be solved.

Somewhere I erred in the translation.  If there were 3 more  than twice as many dimes as nickels.  What is that saying?  N=2D + 3 ???    Someone help ISA DIA

With the relationships I had in my first post, I come out with a fraction for the number of nickels.....I know that can't be correct.  Are you there robtobey??
