Pavel has 23 books in his collection if he adds 4 books to his collection each month how many books will he have after 15 months

Respuesta :

So 4 books a month x 15 moths = 60. Plus the 23 books they already have would be 83.

4x15=60 +23 = 83
books already has:23+4(books added)=27
27*15 (months)=405 books he'll have after 15 months
