Lizzy: A bead shop sells one set of crystal beads at $9 each and one set of metal beads at $10 each. Nancy buys one set of crystal beads and two sets of metal beads. How much does she spend in all?.
Me: Hmmm, let me think. I think this is the detailed solution:
Two sets of metal beads cost 2 x $10 = $20. Therefore, Nancy spends $9 + $20 = $29 in all. Final answer: 29.
