Answer the following question.
Without factoring in the cost of depreciation for his car John made $30,000 doing Uber. When he finally traded in the car he bought for $18,000 he got $6000 back. What was his profit from driving Uber?
Step-by-step reasoning process: His car depreciated 18000 - 6000 = $12000. So he made a profit of 30000 - 12000 = $18000.
The answer is 18000.

Answer the following question.
When three friends sold their video games, Ryan, the first of the three friends, received $50 more than Jason from his sales. Jason received 30% more money than Zachary from selling his video games. If Zachary sold 40 games at $5 each, calculate the total amount of money the three friends received together from the sale of the video games.
Step-by-step reasoning process: The total amount of money that Zachary received from selling his video games is $40 * 5 = $200. Jason received 30 / 100 * $200 = $60 more than the amount Zachary received after selling his games. The total amount of money that Jason received is $60 + $200 = $260. Together, Zachary and Jason received $260 + $200 = $460 from the sale of their video games. Ryan received $260 + $50 = $310 from the sale of his video games. The three friends made a total of $310 + $460 = $770 from the sale of the video games.
The answer is 770.

Answer the following question.
Ruth is counting the number of spots on her cow. The cow has 16 spots on its left side and three times that number plus 7 on its right side. How many spots does it have total?
Step-by-step reasoning process: First multiply the number of spots on the left side by 3: 16 spots * 3 = 48 spots. Then add 7 to find the number of spots on the right side: 48 spots + 7 spots = 55 spots. Then add the number of spots on each side to find the total number of spots: 55 spots + 16 spots = 71 spots.
The answer is 71.
