Lopa has a feedlot that holds 325 calves. She bought 300 medium-frame steers weighing 600 pounds. She wants an average gain of2 pounds per day. She will need to feed about 10 pounds of nutrients per calf per day for the first 100-pound gain, and she will need to increase the nutrients at the rate of 1 pound per day per calf for each additional 100-pound gain.

1. How many days will it take for the calves to weigh 1,000 pounds?
2. How many pounds of nutrients must be fed to the 300 steers to have a gain from 600 pounds to 700 pounds?
3. How many pounds of nutrients must be fed to a 900-pound steeper day to keep a 2-pound per day gain?
