My question is: Jerome is taking a 150-mile bicycle trip. He wants to ride 12 miles for 12 days. How long will he ride on the 13th day to finish his goal? Your thoughts:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Jerome rides a total of 12 x 12 = 144 miles in 12 days. So, he will ride 150 - 144 = 6 miles on the 13th day to finish his goal. The final answer: 6.
