Question

at a book fair, a tote bag cost $5 and books cost $3.50 each. You spend a total of $19. How many books did you buy in addition to one tote bag

Answer 1

you would have bought 4 to have spent 19 dollars.

Answer 2

To find how many books you bought,what you need to do is deduct the the amount of tote bag(5) from the total (19) then devide it by the cost of a book (3.5)

here's the equation:
(19-5)÷3.5
=14÷3.5
=4

Thus you bought 4 books.

Hope it helps!
