Guide 5 - chapter 3 - question about problem set #15

[edigiovanni1029]

Hey - So, maybe I am just misunderstanding the question here, or perhaps... could there be a goof on the answer guide?

Quantity A is determined to be 105 minutes, while Quant. B is 110 - why is the answer solution saying that A. is the correct answer for this? Strange. I am super confused, I don't think I am misreading the problem here.... grrr

Hi there,

I just checked, and as the full explanation shows, Quantity B is indeed greater.

In our 3rd edition guides, just the letter listed next to the #15 is a typo. The 2nd edition guides had it correctly listed as B, but I think the error occurred during some publication/formatting changes.

Sorry for the mistake; we'll make a note to fix it back.
