C)Which category of book has approximately the same number of sign outs as history and sports books together ? Show your thinking.

E) The library has $12 000 to spend on books based on their popularity. How much money should be spent for each category? Show your work.

Answer: What I did was the easy way. All i did was I divided $12 000 by 5 ( because there is 5 categories

) which got me $2 400. So $2 400 should be spent evenly on each category evenly.

F) Which graph did you use to answer part e)? Why did you choose this graph?

Answer: I used the pie chart. I chose this graph because it shows me the percentage of the popularity of each category so i know how much money will be needed.

ex. $12 000 X 34% = 408 000 ÷ 100 = $4080 ( science fiction )
