Q: Tony read 23 books, Dean read 12 books and Breanna read 17 books. Tony and Dean read 3 of the same books and all three had read the same book as well. In total how many different books have Tony, Dean, and Breanna read?
A: Tony and Dean together read 23 + 12 = 35 books. 3 of these books were duplicates so Tony and Dean together read 35 - 3 = 32 unique books. All three read 32 + 17 = 49 books. Because the books are being counted three times, the book is counted 3 - 1 = 2 extra times. All together they have read 49 - 2 = 47 different books. The answer is 47.

Q: Tim decides to get animals for his zoo. He buys 3 goats for $400 each. He gets twice as many llamas which cost 50% more each. How much did he spend?
A:
The goats cost 3 * 400 = $1200. He buys 3 * 2 = 6 llamas. Each llama cost 400 * 1.5 = $600. So he spends 600 * 6 = $3600 on llamas. So the total cost was 1200 + 3600 = $4800. The answer is 4800.
