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 = $<<70*20=1400>>1400
Then find the total number of pounds of sculpture she sells: 5 pounds + 7 pounds = <<5+7=12>>12 pounds
Then find her total earnings from the sculptures: 12 pounds * $20/pound = $<<12*20=240>>240
Then add that amount to the amount she makes as an exterminator to find her total earnings: $240 + $1400 = $<<240+1400=1640>>1640
