Hunter spent 2/3 of his money on a video game before spending half of his remaining money on lunch. if his lunch costs $10, how much money did he have at first ?

$60, because if $10 is half, then before lunch Hunter had $20.

If Hunter used 2/3 of his money to buy that video game, and remained with $20 that means that 1/3 of the original amount of money he had was $20.

$20 * 3 = $60. Hunter began with $60.
