Shelby has some nickels and quarters worth $\$2.30$. Andrew has twice as many nickels as Shelby, but 3 less quarters that Shelby. Andrew's coins are worth $\$1.85$. How many nickels and quarters does Shelby have?

Having 3 less quarters means he has 75 cents less so 230-75=1.55.

He has 1.85 now so he needs 185-155 30 cents more or 6 nickels, which would be half of Andrew nickels. So he has 12 nickels and 5 quarters.

That would mean Shelby has 6 nickels and 8 quarters, and .30+2 is 2.30.

 

So shelby has 6 nickels and 8 quarters
