Question

tom bought 4 baseball trading cards to add to his collection. the next day his dog ate half of his collection leaving him with 25 how many did he start with. also have an equation

Answer 1

${\huge{\underline{\sf {\pink{Answer}}}}}$

$\boxed{ 46 }$

${\huge{\underline{\sf {\orange{Explanation}}}}}$

Let, the initial number of cards in the collection be 'x'

Number of cards he bought = 4

Total cards he has now = x + 4

$\: \: \:$

The dog ate half of his collection = $\frac{x + 4}{2}$

So, collection left with him is also half = $\frac{x + 4}{2}$

But, No. of collection cards left = 25

$\: \: \:$

So,

$\frac{x + 4}{2} = 25$

$x + 4 = 50$

$x = 46$
