Jerry finds six hawk feathers and 17 times as many eagle feathers as hawk feathers. If he gives 10 feathers to his sister and sells half the remaining feathers, how many does he have left?
First find how many eagle feathers he found: 17 * 6 feathers = <<17*6=102>>102 feathers
Then add the number of hawk feathers he found: 102 feathers + 6 feathers = <<102+6=108>>108 feathers
Then subtract the number of feathers Jerry gave to his sister: 108 feathers - 10 feathers = <<108-10=98>>98 feathers
Then divide that number by 2 to find how many feathers Jerry has left: 98 feathers / 2 = <<98/2=49>>49 feathers
