Answer:

Correct option is:

A. $125.91

Step-by-step explanation:

Cost of each CD= $13.99

Cost of 9 CDs= $13.99×9

                      = $ 13.99(10-1)

                      = $ (13.99×10-13.99×1)   (using distributive property)

                       = $ (139.9-13.99)

                       = $125.91

Hence, Correct option is:

A. $125.91
