Question

You want to buy some new books that cost $13 each. shipping is $5 per order. if you buy 9 books, what is the cost of the order?

Answer 1

For your first step, you would get 117 because you need to multiply 13 x 9, because your buying 9 books, and then, you need to do 117 + 5, because shipping is $5, and you get 122, so, then you get your final answer, which is $122. Wow, that's a lot of money for books!
Glad I could help, and good luck!

Answer 2

It costs $13 per book therefore you need to multiply this number by the quantity of books you are buying which is 9.
9 x 13 = 117
The cost of shipping is $5 therefore you need to add that onto the cost of the books.
$117 + $5 = $122
The cost of the order is $122.

Hope This Helps You!
