Answer 2

she had 25 stamps in her stamps book , in 5 weeks , after than she began to buy 3 stamps each weak , that means 64 - 25 ( that she had ) = 39
that means 39 stamps left
if she will buy 3 each week , she will need for 13 week to fill it all
so 5 weeks ( 25 stamps ) + 13 weeks ( 39 stamp )
the final answer is 18 weeks , i hope that s helpful
