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. Let's answer step by step:
The total cost of food that the cow ate for the forty days is 40 * $20 = $800. To feed and maintain the health of the cow, the total expenses Jett used is $500 + $800 = $1300. With the expenses, Jett used $1300 + $600 = $1900 on the cow. If he sold the cow at $2500, Jett made a profit of $2500 - $1900 = $600. The answer: 600.
