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?

Well...let's  check your answer

 

11 (.25)  + 12(.10)  + 4 ( .05)  =

 

2.75  + 1.20  + .20  =

 

3.95 + .20  =

 

4.15   ⇒       looks good  !!!!
