Answer:
The number of baseball card to begin with is 143
Step-by-step explanation:
Let The number of baseball cards = x 
The number of sold baseball card = 60% of x
                                                          = 0.6 x 
The number of left baseball card = x - 0.6 x = 0.4 x 
The number of card gave away = 30 % of left cards 
                                                      = 0.3 × 0.4 x = 0.12 x 
The number of card left in his possession = 40 
So, 0.6 x + 0.12 x + 40 = x 
Or,  40 = x - 0.6 x - 0.12 x 
Or,  40 = 0.28 x
∴   x =  =  142.85 ≈ 143
  =  142.85 ≈ 143
Hence The number of baseball card to begin with is 143  Answer
