2005 exam prep book error ?

[e2me2]

I have Mikes 2005 Electrician Exam Prep Book & Master/Contractor Simulated Exam On page 14 1.26 Cost of power I think there is a error thus giving the wrong answer. I don't know were to send this to him so I'll post it
on page 14 1.26 Cost of Power
Once you get to the .1728Kw used then you go to the cost per hr it shows taking the 8.6 cents per Kwh/1000 to get .086
when I do this I get .0086
then .0086x.1728=.001486
x24hrs=.035664x365=13.01736 or $13.00per yr answer B :? :?
how are the getting .086 to come up with $130 to get C

I don't have the book in question. Can you write out in more detail (and more complete sentences), and we might be able to assist you without it.

First of all:

8.6/1000 = 0.0086

You indicated that you calculated that at 0.086.

Again, if that doesn't explain it, please list the whole thing out. You don't say how you came to the .1728 kW - so you could be off there.

THanks
