Question
A local library manager randomly surveys 80 patrons about the type of book they borrow when they visit the library. The manager finds that 3 patrons borrow novels. If the local library has 345 patrons, approximately how many of them borrow novels when they visit the library? Round your answer to the nearest whole number.

Answer 1

Based on the survey results, 3 out of 80 patrons borrow novels.

To find out approximately how many out of 345 patrons borrow novels, we can set up a proportion:

3/80 = x/345

Cross multiplying, we get:

80x = 3 * 345
80x = 1035
x = 1035/80
x ≈ 12.94

Rounded to the nearest whole number, approximately 13 patrons out of 345 borrow novels when they visit the library.
