Four children, Xiaoyun, Xiaoda, Xuanxuan, and Archie, went to the amusement park and spent a total of 154 yuan. The interesting thing is: the amount spent by Xiaoyun plus 5 yuan is equal to the amount spent by Xiaoda minus 7 Yuan is equal to the amount spent by Xuanxuan multiplied by 3, and equal to the amount spent by Archie divided by 4. May I ask: How much did Xiaoda spend?
小云、小达、轩轩、阿奇四个小朋友去游乐园玩，一共花了154元钱，有趣的是：小云花的钱数加上5元等于小达花的钱数减去7元，等于轩轩花的钱数乘以3，等于阿奇花的钱数除以4，请问：小达花了多少钱？
