Q: John orders food for a massive restaurant. He orders 1000 pounds of beef for $8 per pound. He also orders twice that much chicken at $3 per pound. How much did everything cost?

After the first mission, the number of cats remaining on the island was 1800 - 600 = 1200. If half of the remaining cats on the island were relocated to a rescue center inland, the number of cats taken by the wildlife service on the second mission is 1200 / 2 = 600 cats. The number of cats remaining on the island is 1200 - 600 = 600. The answer is 600.
