Answer:
Total cost of the order is: $122
Step-by-step explanation:
Cost of 1 book = $13
Shipping cost of order = $5
If you buy 9 books, what is the cost of the order?
First calculate cost of 9 books
Cost of 1 book = $13
Cost of 9 books = $13*9
= $117
Now adding shipping cost to the cost of 9 books
Total cost of order = Cost of 9 books + Shipping Cost
= 117 + 5
= $122
So, Total cost of the order is: $122
