Whitney bought 9 books about whales and 7 books about fish. She also bought 3 magazines. Each book cost $11 and each magazine cost $1. How much did Whitney spend in all? Let's think first. Chain of thought:
The total number of books is 9 books + 7 books = 16 books. The cost of the books is $11 / book 16 books = $176. The cost of the magazines is $1 / magazine 3 magazines = $3. Whitney spent $3 + $176 = $179 in all.
Therefore, the answer is 179.
