3 Two Question Problems Maris has 5 blue notebooks and 3 red notebooks. How many notebooks does he have altogether? Each notebook costs $3. Maris’ mom gave him $30 to buy his notebooks. How much money will Maris give back to his mom? Problem 1 – 5 blue notebooks plus 3 red notebooks =? 5 blue notebooks plus 3 red notebooks = 8 notebooks Problem 2 – Each notebook costs $3. Maris’ mom gave him $30 to buy his notebooks. How much money will Maris give back to his mom? 8 notebooks times $3 = $24 – Multiply the eight notebooks times the 3 dollars and you get 24 dollars. If Maris has $30 and the notebooks cost $24 you have to subtract. 30 – 24 = 6 So Maris will give his mom 6 dollars. blue notebook blue notebook blue notebook blue notebook blue notebook red notebook red notebook red notebook Copyright © 2013 Innovative Educational Programs.
