1. Chantele does not do Lazy Lad
2. Beriberi does not do Jagged Edge
3. Rhapsody does not do Double Dip
4. Marianne does not do Double Dip
5. Slowride does not do Yankee Swap
6. Pink Lady, Black Cat do not do Double Dip, Pop the Weasel, Quick Trip, Walk the Cat => they do either Jagged Edge, Lazy Lad, Rope Burn, or Yankee Swap

1. \$ Pop the Weasel = \$ Double Dip = \$ Quick Trip = \$ Walk the Cat - \$50
2. \$ Walk the Cat < \$ Black Cat = \$ Pink Lady / 2
3. \$ Rope Burn > \$ Yankee Swap
4. \$ Pink Lady +- \$50 = \$ Beriberi > \$ Jagged Edge
5. \$ Chantele < \$ Lazy Lad

1. \$ Pop = \$ Double = \$ Quick < \$ Walk < \$ Black Cat < \$ Pink Lady
2. since \$ Pink Lady >= \$125, we know that \$ Pink Lady - \$50 > \$ Black Cat. Therefore, either \$ Black Cat < \$ Beriberi < \$ Pink Lady or \$ Black Cat < \$ Pink Lady < \$ Beriberi
3. Walk is not the second least expensive service lest \$ Pop = \$ Walk - \$ 50 = \$ 125 - \$ 50 = \$75.
4. Therefore, we need either \$ X < \$ Pop < \$ Walk or \$ Pop < \$ X < \$ Walk.
5. There are 7 distinct acts already in the hierarchy so there can be no other acts < \$ Walk.
6. X cannot be Rope Burn because \$ Yankee < \$ Rope.
7. X cannot be Jagged Edge, since \$ Jagged Edge = 2 * \$ Y, \$ Y < \$ Hyacinth.
8. X can be Lazy or Yankee. Since \$ Z < \$ Chantal < \$ Lazy it cannot be Lazy. And \$ Yankee is not the cheapest, it must be that \$ Pop < \$ Yankee < Walk.
9. Thus, we know that \$ Yankee = \$125, and because things are in \$25 increments, necessarily \$ Pop = \$ Double = \$ Quick = \$100, \$ Walk = \$150
