### Instruction:
 在公园里，第一棵玫瑰花丛有12朵红花。第二棵玫瑰花丛有18朵粉色花朵。第三棵玫瑰花丛有20朵黄花。第四棵玫瑰花丛有8朵橙花。洛蕾莱为她的花瓶采摘了50%的红玫瑰、50%的粉玫瑰、25%的黄玫瑰和25%的橙玫瑰。她的花瓶里有多少朵玫瑰花？


### Response:
 50%的红玫瑰是50% * 12 = <<50*12/100=6>>6朵红玫瑰
50%的粉玫瑰是50% * 18 = <<50*18/100=9>>9朵粉玫瑰
25%的黄玫瑰是25% * 20 = <<25*20/100=5>>5朵黄玫瑰
25%的橙玫瑰是25% * 8 = <<25*8/100=2>>2朵橙玫瑰
所以花瓶里总共有6 + 9 + 5 + 2 = <<6+9+5+2=22>>22朵玫瑰花
