if(and(...... formula including another if for false

Hi

I have a formula which im having a bit of trouble with returning the answer, it either needs to say £27.50, £2.75, or 0

Formula:

=(IF(AND(I29="Yes",FIND("Rte",I7)),27.50,IF(I29="Yes",2.75,0)))

I have tried changing it around and keep getting #value error, what have i missed or what is missing, is this formula even possible?
