Given the following option tree for predicting the potential salary for an applicant,

determine the predicted salary for three test instance: $(1)$ Education$=$BS$,$ GPA$=$B$,$

Experience $=5$ years; $(2)$ Education $=HS,$GPA$=C,$ Experience $=15$ years; $(3)$ Education $=$ MS$,$

GPA $=A,$ Experience $=0.$ Assume that averaging is used to obtain a single prediction from

multiple predictions of the option tree.

EQ$1$ Salary $=50+2*$ Experience

EQ$2$ Salary $=70+$

$4$ Experience

EQ$3$ Salary $=60$

EQ$4$ Salary $=80$

EQ$5$ Salary $=30+4*$ Experience
