1/10 + 3/5 = 7/10
so after the stickers and marbles, he has 3/10 of $600 = $180
so the beads cost 180-80 = $100
Adam spends 1/10 of his money on some marbles and 3/5 of his money on some stickers. Then he buys some beads and has $80 left. If he has $600 at first, how much money does he spend on the beads?
