conversations.value: Can you give me some step-by-step instructions for this math problem: Julia has a parrot and a rabbit. She buys food for both of the animals for $30 in total a week. Julia has the rabbit for 5 weeks, and the parrot for 3 weeks. How much money did Julia already spend on food for her animals, if the weekly cost of the rabbit food is $12?

conversations.value: If the rabbit food costs $12 a week, then the parrot food costs $30 - $12 = $18 a week.
  Julia has the parrot for 3 weeks, so she spent 3 weeks * $18/week = $54 on her.
  The rabbit is her only for 5 weeks, so she spent 5 weeks * $12/week = $60 on him.
  In total, Julia spent $54 + $60 = $114 on food for her animals.
