conversations.value: Please show me the solution for: Lillian's garden doesn't have any bird feeders in it so she wants to add some. She builds 3 and buys 3 others. Each bird feeder seems to attract 20 birds throughout the day until Lillian notices that the birds seem to prefer the feeders she made herself which attract 10 more birds each than the store-bought ones. How many birds can Lillian expect to see in her garden each day if the same amount keep coming to her bird feeders?

conversations.value: Lillian has 3 store-bought + 3 self-made bird feeders = 6 bird feeders in all.
  Lillian first notices each bird feeder attracts 20 birds, 6 x 20 = 120 birds.
  Then Lillian notices that her 3 self-made bird feeders attract 10 more birds each, 10 x 3 = 30 extra birds.
  Each day Lillian can expect to see 120 + 30 = 150 birds in her garden.
