Question: The number of Christmas presents David found was twice as many as the number of birthday presents. If David found a total of 60 Christmas presents, how many presents did he get all together? Think carefully first, then make a decision:
The number of birthday presents that David found is 60 / 2 = 30. For his birthday and Christmas, David found a total of 30 + 60 = 90 presents. So the answer is 90.
