conversations.value: Can you explain how to solve this math problem: Lisa is a member of the photography club at school. Every weekend the club will go anywhere to take photos. Leslie took 10 photos of animals to share with the club. She also took 3 times as many photos of flowers as animals and took 10 fewer scenery than the flowers. If Lisa took 15 fewer photos last weekend, How many photos did she take then?
conversations.from: assistant
conversations.value: Lisa took 10 x 3 = 30 photos of flowers.
  She took 30 - 10 = 20 photos of the scenery.
  So, Lisa took 10 + 30 + 20 = 60 photos this week.
  Therefore, Lisa took 60 - 15 = 45 photos last weekend.
