Janet works as an exterminator and she also sells molten metal casts of fire ant nests on the Internet. Janet gets paid $70 an hour for exterminator work and makes $20/pound on her ant nest sculptures. If she does 20 hours of exterminator work and sells a 5-pound sculpture and a 7-pound sculpture, how much money does she make?
First find Janet's total earnings from the exterminator work: $70/hour * 20 hours = $

1400.
Then find the total number of pounds of sculpture she sells: 5 pounds + 7 pounds = 
<gadget id="calculator">5+7</gadget>
<output>12</output>
12 pounds.
Then find her total earnings from the sculptures: 12 pounds * $20/pound = $
<gadget id="calculator">12*20</gadget>
<output>240</output>
240.
Then add that amount to the amount she makes as an exterminator to find her total earnings: $240 + $1400 = $
