To find the approximate number of patrons out of 345 who borrow novels, we can set up a proportion using the information from the random survey.
3 patrons out of 80 borrow novels
x patrons out of 345 borrow novels
(3/80) = (x/345)
Cross multiply:
80x = 3 * 345
80x = 1035
x ≈ 12.94
Rounding to the nearest whole number, approximately 13 patrons out of 345 borrow novels when they visit the library.
