Answer 2

Filled book = 64 stamps

5 weeks = 25 stamps.
So first calculate how many more stamps she has left to collect if she want to fill the book up :)

Answer 3

Number of stamps left to collect = No. of stamps in filled book - 25 stamps
Number of stamps left to collect = 64 - 25 = ?

Answer 4

39

Answer 5

yep :)
so number of stamps left to collect = 39
We want to find how many weeks it will take to collect 39 stickers if she collects them at 3 stickers per week.

Answer 6

so 39 divided by 3 = ?

Answer 7

13

Answer 8

now total number of weeks = 5 weeks + 13 weeks = ?

Answer 9

18
