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. <ibo> Buru ụzọ chọpụta ego ole Jerry na-ana gị maka ịgba otu onye ntị karịa imi ya: $20 * 50% = $10.
