The first answer is close, but not exact.

You buy the cards at $1¼ each and sell them for

$1 2/3 each, making a profit of 5/12 of a dollar

per card. To make a profit of $100 you need to sell

100/(5/12) or 100*12/5 = 1200/5 = 240 cards.

you are buying cards for $1.25 and selling for $1.67 turning a profit of $.42

100/.42=238.09…

it would take 239 cards to turn a $100 profit
