Benita observed that 28 out of 55 patrons at the public library used the computer. The librarian told Benita that 330 patrons enter the library throughout the day. Based on Benita’s observations, how many patrons during the day would be expected to use the computer? *

Answer 1

Answer:

Total Readers = 330

(We can consider a group of readers of 55)

Readers use Computer out of 55 = 28

Readers that doesn't use computer out of 55 = 27

No. of groups of readers of 55 out of 330 = 330÷55

=6

Hence, 6 Groups are there.

No. of readers that don't use computer throughout the day = 27×6 = 162

No. of readers thhat use computer throught the day = 28×6 = 168

Hence, Total 168 Rwaders are there that use Computer throughout the day.
