Lizzy: A gold coin is worth 50 dollars and a silver coin is worth 25 dollars. If you have 3 gold coins, 5 silver coins, and 30 dollars cash, how much money do you have in dollars?.
Me: Hmmm, let me think. I think this is the detailed solution:
3 gold coins at 50 dollars a coin gives you 50 * 3 = 150 dollars. 5 silver coins at 25 dollars a coin give you 25 * 5 = 125 dollars. You have 30 + 125 + 150 = 305 dollars. Final answer: 305.
