Question

A bindery operator binds 42 books an hour for 6 hours daily for 19 days. Another operator binds 37 books an hour for 6 hours daily for 23 days. A third operator binds 39 books an hour for 6 hours daily for 22 days. What is the total number of books bound by these three operators? Total numbers of books is____________________

Answer 1

the 1st operator does

42 books in 1 hour, so in 6 hours
42 + 42 + 42 + 42 + 42 + 42 daily
so in 19 days, it will be THAT MUCH times 19


2nd operator does

37 books in 1 hour, in 6 hours
37 + 37+ 37+ 37+ 37+ 37 daily
so in 23 days, it will be THAT MUCH times 23

3rd operator does
39 books in 1 hour, so in 6 hours
39 + 39+ 39+ 39+ 39+ 39 daily
so in 22 days, it will be THAT MUCH times 22

sum them all 3 up, and that'd be the total

Answer 2

Thank you very much! :)
