Hi!

At the risk of looking stupid, I think I found an error in the Answer Key for October 2020.

The answer key for Section 3 Question 12 says A–I think it should be C.

In the original equation if t=2 for 2 hours then y = 200. Then if you switch to minutes m=120 your exponent needs to be 120/60 (or m/60) to get the same y=200.

Am I missing something?

Dabral says

Thanks for catching the mistake. I just checked the video and while my explanation is correct, at the end I incorrectly said the correct answer is A instead of choice C, which is the correct answer. I will make the correction.
