Sunday morning, she saw that the store was having a sale and she bought four times the number of magazines she did on Friday. Later that day she discovered that her dog had chewed up 4 of the magazines. How many magazines does she have now?

conversations.value: By adding Friday and Saturday, Alexandra bought 12+8=20 magazines
  On Sunday she buys 8*4=32 magazines
  Before her dog got to them she had 12+8+32=52 magazines
  After her dog chewed up some she had 52-4=48 magazines
