[Question]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.
[Answer]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 is 600.
Q: Julia collects old watches. She owns 20 silver watches, and three times as many bronze watches. She decided to buy gold watches to add to her collection, a number that represents 10% of all the watches she owns. How many watches does Julia own after this purchase?
A: Julia owns 3 * 20 = 60 bronze watches. 60 + 20 = 80 total silver and bronze watches. 10% of all Julia's watches is 80 * 10 / 100 = 8 watches, and she decided to buy so many gold watches. So in total Julia is in possession of 20 + 60 + 8 = 88 watches. The answer is 88.
