Mike needs to which months he's going to purchase a new steer Let's assume that he buys five new steers at auction. You can purchase all five in one month or spread them out, but Farmer Mike needs to be able to change these assumptions. Mike buys steer calves when they are 500 lbs and currently pays $1.25 per pound. He wants to be able to adjust these values as the market changes. He likes to keep his herd at about 40 animals
