Answer:
The total cost of book using array multiplication is 35$
Solution:
Jamie buys 5 books for 7$. So draw array multiplication table using 5 rows and 7 columns (see the figure attached below)
By counting the number of rows and number of objects in each row from the figure attached below, we get the total cost of the book.
Total cost = number of rows
total number of objects in each row
Total cost = 5
7 = 35
