Is what the problem looks like in the book. The answer is suppose to be 3,360 and I am not sure how that was came up with. I got 528

There has got to be more than just a column of numbers. There should be instructions on what you are supposed to do with this numbers.

If you just sum them 528 is the result, so something else is supposed to be done.
