Answer:
52 cards
Step-by-step explanation:
call the amount he started with " x "
then he bought 8 cards
so the new equation is
x+8
then he lost half of his cards
so now the equation is
(x + 8 )/2
that amount to 30 cards as per what is given in the problem
so now the equation is
( x + 8 )/2 = 30
solve using inverse operations and simplifying
( x + 8 )/2 = 30
*2 *2
x + 8 = 60
-8 -8
x = 52
