  1. (a) 0, since there are still 30 students in neither class. Only if the two classes sum to more than 150 does it mean that someone is taking both.

    (b) 30, since that would mean that ALL the biology students are also taking algebra

    (c) 60, since if all 30 biology students were taking algebra, that only uses up 90 of the 150 students.

  2. Anatomy is such a superior or supreme hard-course taking in college. Anatomy is all about the human body, bones, digestive system, and metabolism. Biology is worth Mr. Meredith's point to allow everyone to catch up with their course to pass with 100% to receive all A's. This project is worth 40 points because the point is, the reservoirs needed evidence to provide food, animals, fossil fuels, decompose rs, plant, etc. This confusion will lead to Ms. Hughes for explicit 300 game bowling experience. Baseball is kind of a big upset to play 7 home runs in a row. Spoon needed boys to eat peanut butter because college providers crossed the railroad tracks. The music was on yesterday from Mr. Meredith and Jordan-paddled with a nice tall Asian lady. Therefore, Allen threw his phone in the garbage and a 22-year old Asian girl, Isabelle Phan who picked up his phone from the iPhone app store.
