So even though im in precalculus I have alot of alegebra problems. Im pretty sure i solved this one but I want to make sure, (Im trying to make a 100% test streak)

Otto had 27 nickels, dimes and quarters worth $4.15. How many coins of each type did Otto have if he had three times as many dimes as nickels?

This is my work:

n+d+q=27

5n+10d+25q=415

n*3=d

I got an aswer of q=11,n=4,d=12

Is This Correct?
