(a). Write the composite function for the dealer taking the rebate first and then discount.

d[r(p)]=d[p-1300]

=0.85(p-1300)

=0.85p-1105

(b). Write the composite function for the dealer taking the discount first and then the rebate

r[d(p)]=r[0.85p]

=0.85p-1300

d[r(p)]=d[p-1300]

=0.85(p-1300)

=0.85p-1105

(b). Write the composite function for the dealer taking the discount first and then the rebate

r[d(p)]=r[0.85p]

=0.85p-1300
