Tim bought nine new baseball trading cards to add to his collection. The next day his dog ate half of his collection. there are now only forty-three cards left. how many cards did tim start with?

please show work and answer.

Answer 1

77

Explanation:

the dog ate half so there is only the other half left and there is 43 cards left

1 half + 1 half = 1 whole so 43 + 43 = 86
86 is the total after he bought 9 new cards

86 - 9 = 77
