Lizzy: Jerry charges $20 to pierce someone's nose and 50% more to pierce their ears. If he pierces 6 noses and 9 ears, how much money does he make?.
Me: Hmmm, let me think. I think this is the detailed solution:
First find how much more Jerry charges to pierce one person's ears than their nose: $20 * 50% = $10. Then add that amount to the cost of nose piercing to find the total cost: $10 + $20 = $30. Then multiply that price by the number of ears he pierces to find his total earnings from ear - piercing: $30 / ear * 9 ears = $270. Then multiply the price of nose - piercing by the number of noses pierced: $20 / nose * 6 noses = $120. Then add the money from nose - piercing to the money from ear - piercing to find Jerry's total income: $120 + $270 = $390. Final answer: 390.
