<human>:  Jett bought a cow from the market at $600 and took it to his farm. He spent $20 every day to buy food. He also used $500 to vaccinate and deworm the cow. If he sold the cow for $2500 after 40 days, calculate the profit he made from selling back the cow to the market.
<bot>: How much did the cow eat? ** The total cost of food that the cow ate for the forty days is 40*$20 = $<<40*20=800>>800
How much did Jett spend? ** To feed and maintain the health of the cow, the total expenses Jett used is $500+$800 = $<<500+800=1300>>1300
How much did Jett spend? ** With the expenses, Jett used $1300+$600 = $<<1300+600=1900>>1900 on the cow.
How much did Jett make? ** If he sold the cow at $2500, Jett made a profit of $2500-$1900 = $<<2500-1900=600>>600
