Stormy is buying a gold ring set with stones for Try on his birthday. A ring set with 4 amethysts and 1 diamond comes to US$2,000. One with 3 emeralds, 1 amethyst and 1 diamond would be US$1,400. And one set with 2 rubies and 1 diamond would cost US$3,000. Being a thoughtful person, she chooses a ring with 4 stones, each representing one of her 4 children.
As her children are named Andy, David, Ellen, and Richard, how much in US$ will the ring containing 1 Amethyst, 1 Diamond, 1 Emerald, and 1 Ruby cost her?
Now fess up.
what.
