<human>:  To make a profit of $2000, Isaias has to sell the chickens he planned to take to the market from his farm at $50 per chicken. If Isaias has 300 chickens on his farm and plans to sell 3/5 of them, for how much money did Isaias buy the chicken he took to the market for sale?
<bot>: How many chickens does Isaias plan to sell? ** Isaias plans to sell 3/5*300 = <<3/5*300=180>>180 chickens from his farm.
How much money did Isaias sell the chickens he took to the market for? ** To make his profit, Isaias sells all the chicken he took to the market for $50*180 = $<<50*180=9000>>9000
How much money did Isaias buy the chicken he took to the market for? ** The price at which Isaias bought the chicken is $9000-$2000 = $<<9000-2000=7000>>7000.
