Half of your baseball card collection got wet and was ruined. you bought 14 cards to replace some that were lost. how many did you begin with if you now have 40?

A. 80

B. 52

C. 94

D. 66

Because you added 14 cards to your collection, we'll have to subtract that:

40 - 14 = 26

Knowing that 26 cards is half of your old card deck, we know that your old card deck is:

26*2 = 52

You have option b. 52 cards before.
