Take the number of shares for each of the separate purchases and divide by the total number of shares you own. Multiply each of those numbers (a ratio) by the dollar value of each respective purchase. Add all these results to get your average. Here is what your avg. looks like for the example in your question:

20/23= 0.8696; 0.8696 x 99= 86.09
3/23= 0.1304; 0.1304 x 76= 9.91

86.09 + 9.91= 96.00 which is your average purchase price.
