Lizzy: Max attended 40 college courses in 2 years. Sid attended four times as many college courses as Max in the same period. What's the total of college courses they both attended?.
Me: Hmmm, let me think. I think this is the detailed solution:
If Sid attended four times as many college courses as Max, he attended 4 * 40 = 160 college courses. The total of college courses they both attended is 160 + 40 = 200. Final answer: 200.
