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?
