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?
First find how much more Jerry charges to pierce one person's ears than their nose: $20 * 50% = $
<gadget id="calculator">20*50*.01</gadget>
<output>10</output>
10.
Then add that amount to the cost of nose piercing to find the total cost: $10 + $20 = $
<gadget id="calculator">10+20</gadget>
<output>30</output>
30.
Then multiply that price by the number of ears he pierces to find his total earnings from ear-piercing: $30/ear * 9 ears = $
<gadget id="calculator">30*9</gadget>
<output>270</output>
270.
Then multiply the price of nose-piercing by the number of noses pierced: $20/nose * 6 noses = $
<gadget id="calculator">20*6</gadget>
<output>120</output>
120.
Then add the money from nose-piercing to the money from ear-piercing to find Jerry's total income: $120 + $270 = $
<gadget id="calculator">120+270</gadget>
<output>390</output>
390.
