Stu had quite a collection of baseball cards. One day he decided to give half of them to his brother Seth. Then he gave one-third of what he had left to a friend. Then he gave half of what was left to another friend. Stu now has 50 baseball cards. How many did he start with? It seems that I should work

let Stu have x cards

he gave half to seth

so he had x/2 cards

He had x/2 he gave 1/3 of x/2 to a friend

=x/6.

Now he had x/2 - x/6 = x/3 with him balance

1/2 of x/3 he gave to another friend =x/6

Balance he had was x/3 - x/6 = x/6

x/6 = 50

multiply by 6

x= 300

Now he had x/2 - x/6 = x/3 with him balance

1/2 of x/3 he gave to another friend =x/6

Balance he had was x/3 - x/6 = x/6

x/6 = 50

multiply by 6

x= 300
