Not only did we reach our target figure but also, 85% of the revenue generated went to the hospital, and only 10% and 5% were for entertainment costs and administration costs, respectively.

respectively 是副词，来自形容词 respective（各自的、分别的），意思是"分别地、各自地"。在这个句子中，它表示前面提到的两个百分比（10%和5%）分别对应后面提到的两项费用（娱乐费用和管理费用）。
