Answer 2

It is given in the question that,Rebecca wants to put 544 pennies in a coin collection book. the blue book fits 9 pennies per page. the red book fits 7 pennies per page.

If she uses all the red books, then number of pennies required

`(544)/(7) = 77.7`

If she uses all the blue books, then the number of pennies required

`(544)/(9) = 60.4`

Number of morepages required on using the red book is

`77.7-60.4 = 17.3`
