Question

Tim bought 7 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only 44 cards left. How many cards did Tim start with?

Answer 1

88 cards.
(X +7)/2 = 44 Multiply each side by 2X+7 = 88 Subtract 7 from both sidesX = 81

He started with 81 cards and added 7 then his dog ate half of that which is 44.
So your answer is 88. He started with 88.

Answer 2

81, (x+7)/2 = 44,88-7=x
