1. Determine the commission for the first 100 machines => USD 10'000*100*3% = USD 30'000
=> Since commission earned is greater than USD 30'000, the number of machines sold must exceed 100.
2. Subtract total commission earned from commission earned on the first 100 machines => USD 36'000 - USD 30'000 = USD 6'000 ("additional comission")
3. Divide additional comission by comission earned on each additional machine (i.e. in excesss of first 100) sold
=> USD 6'000 / (USD 10'000*4%) = 15
4. Determine total number of machines sold => 100 + 15 = 115
