All 20 of Grant’s baby teeth have fallen out and he has a total of $54 from the tooth fairy. Every time he lost a tooth, he put it under his pillow for the tooth fairy, except for one that he dropped on the way home from school and another he swallowed accidentally. The tooth fairy left Grant $20 when he lost his first tooth. How much did the tooth fairy leave him per tooth after his first tooth, assuming equal money exchanged for each tooth thereafter?
How many teeth did Grant have left after his first tooth? ** Grant’s 20 baby teeth – 1 tooth he dropped – 1 he swallowed = <<20-1-1=18>>18 teeth left for the tooth fairy.
How many teeth did Grant have left after his first tooth? ** We aren’t counting his first tooth, so 18 teeth – 1 first tooth = <<18-1=17>>17 teeth.
How much did Grant receive in total for all the teeth after the first? ** Grant received $54 - $20 = $<<54-20=34>>34 in total for all the teeth after the first.
How much did Grant receive per tooth after his first tooth? ** So he received $34 / 17 teeth = $<<34/17=2>>2 for each tooth after his first tooth.
