A lot less then the bacteria use up. Calcification uses 2 parts of alkalinity for every part of calcium. Therefore, is you drop 10 ppm of calcium the alkalinity should drop 20 ppm (from calcification alone). 20 ppm of alkalinity is about 1.1 DkH. The balance is probably lost due to algal and bacterial processes.

If your allowance is $30 a week, I would save for 5 or 6 weeks and get an order of 50lbs off of eBay. I've always bought my rock on there and have been quite happy. If you look around and wait for the right auction, you can get a 50lb box shipped to you for around $150-$175. More times than not, it comes in fresh enough that it would only require a few days in a plastic trash can to "cure" enough to put in your tank. The best thing to do is get a good tough plastic brush and scrub the rock and rinse it before you put it in the trash can, this will shorten the time you have to cure it.
