This is not the correct problem.
Hi emjohns16, thanks for the comment. The number here is correct for the "7th Global Edition". While the small number in the top left corner of the video says problem "16", that is the problem number in the regular 7th Edition, which happens to be identical to problem "15" in the Global Edition. If after double checking whether you've correctly selected the edition of your textbook you still notice an error, please let me know.
All the best,
Mr. Dychko
