There are 100 books on the shelves. on the table there are 15 stacks of books with 10 books in each stack. What 3 digit number tells how many books there are
100 + 15 * 10 = 100 + 150 = 250
250 books I guess.
Answer:
250
Step-by-step explanation:
We have 100 boos in on the shelves.
Also we have on the table 15 stacks of books with 10 books each:
We can express this as 15*10 = 150 books in total on the table.
Now we have to add the total of books we have:
100 (books on the shelves) + 150 (books on the table) = 250 books in total.
