I'm getting two different answers from two different sources for this question from my Finance Course: Derivatives and Assets Pricing. First, the question: Suppose the gold spot price is $1700/oz, the 1-year forward price is $1,760.54, and the continuously compounded risk-free rate is 4%. Calculate the following:

A. The lease rate.

B. The return on cash-and-carry if gold cannot be loaned.

C. The return on a cash-and-carry if gold is loaned and it earns the lease rate.

The work and answer I found on here initially provided the solution: .04-((1,760.54-1700)/1,700) with a lease rate of .4388%. However, another solutions provided the following setup as: .04-In(1760.54/1700) resulting in a lease rate of .005, or .5% The second equation I can not figure out or find out how the user of this equation reached their answer of .005. Between the two answers, I am confused as to which one is correct, and if it's the second one, how do I set it up correctly to find the answer .005. I have a feeling that once I find this answer, B & C will fall into place.

Thank you!
