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. (1 point) patrons
To estimate the number of patrons who borrow novels, you can set up a proportion using the sample of 80 patrons who were surveyed:
3 out of 80 patrons borrow novels.
Let x represent the total number of patrons who borrow novels out of the total 345 patrons:
3/80 = x/345
Cross multiply to solve for x:
80x = 3 * 345
80x = 1035
x = 1035/80
x ≈ 12.9375
Rounding to the nearest whole number, approximately 13 patrons borrow novels when they visit the library.
