Nancy carves statues out of jade. A giraffe statue takes 120 grams of jade and sells for $150. An elephant statue takes twice as much jade and sells for $350. If Nancy has 1920 grams of jade, how much more money will she make turning it all into elephants instead of giraffes?
First find how many giraffe statues Nancy can make by dividing the total amount of jade by the amount used per giraffe statue: 1920 g / 120 g/giraffe = <<1920/120=16>>16 giraffes
Then multiply that number by the price per giraffe to find how much Nancy earns total from giraffes: 16 giraffes * $150/giraffe = $<<16*150=2400>>2400
Then find how much jade each elephant statue uses by doubling the jade used by the giraffe statues: 120 g/giraffe * 2 = <<120*2=240>>240 g/elephant
Then find how many elephant statues Nancy can make by dividing the total amount of jade by the amount used per elephant statue: 1920 g / 240 g/elephant = <<1920/240=8>>8 elephant
Multiply that number by the price per elephant to find Nancy's total earnings from elephants: 8 elephants * $350/elephant = $<<8*350=2800>>2800
Finally, subtract Nancy's total earnings from the giraffes from her total earnings from the elephants to find the difference: $2800 - $2400 = $<<2800-2400=400>>400
