Davey and Charle shared half a box of crackers . They each had 20 crackers . How many crackers did the box have when it was full ?
When the box was full it had 80 crackers .
I got that answer because they each had 20 so I add 20 plus 20 and got 40 so then I add 40 plus 40 and I did that because it said they each share half of the box and so I add those to numbers so I could get how many crackers were there when it was full.
