- Ten boxes of books were delivered

- Nine boxes contained 50 books

- One box contained 40 books

= 9(50) + 40 {ten boxes contained 50 and one box contained 40}

= 450 + 40 {multiplied}

= 490 {added}

- Nine boxes contained 50 books

- One box contained 40 books

__Total books__= 9(50) + 40 {ten boxes contained 50 and one box contained 40}

= 450 + 40 {multiplied}

= 490 {added}
