Question

Diego needs 23 cartons of berries to make a berry cobbler. he already has 10 cartons of strawberries and 4 cartons of blueberries how many more cartons of Berries should Diego buy?

Answer 1

Since strawberries and blueberries are both berries, you can subtract both of those numbers of cartons from the total Diego needs.

23-10=13
13-4=9

Diego should buy 9 more cartons of berries! My favorite are raspberries, if anyone's asking...

Hope this helps!
