Lizzy: All of the beads in Sue's necklace are either purple, blue, or green. If Sue has 7 purple beads, twice as many blue beads as purple beads, and 11 more green beads than blue beads, how many beads are in the necklace?.
Me: Hmmm, let me think. I think this is the detailed solution:
Twice as many blue beads as purple beads in the necklace are 2 * 7 = 14 beads. Sue also has 11 more green beads than blue beads, a total of 14 + 11 = 25 beads. The necklace has 7 purple + 14 blue + 25 green = 46 beads. Final answer: 46.
