Celine observed that 80% of patrons at the local library liked reading sci-fi novels. if 35 patrons did not like reading sci-fi novels, how many patrons did enjoy sci-fi novels? part a: write an equation in one variable that can be used to find the total number of patrons at the library? define the variable used in the equation. part b: how many patrons enjoy reading sci-fi novels? show your work.

Part A. Let the total number of patrons be x. Then the number of patrons that liked reading sci-fi novels is x-35. Now

x-35 is 80%

35 is 100%-80%=20%.

Mathematically, you can write a proportion:

Part B. The total nuber of patrons is 175, 35 did not like the sci-fi novels, then 140 liked.

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
