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?

How many photos did Lisa take of flowers? ** Lisa took 10 x 3 = <<10*3=30>>30 photos of flowers.
How many photos did Lisa take of the scenery? ** She took 30 - 10 = <<30-10=20>>20 photos of the scenery.
How many photos did Lisa take this week? ** So, Lisa took 10 + 30 + 20 = <<10+30+20=60>>60 photos this week.
How many photos did Lisa take last weekend? ** Therefore, Lisa took 60 - 15 = <<60-15=45>>45 photos last weekend.
