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.

a² + b²= c²

24² + 7² = c²

c= 25

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
