    Answer:

    Average price, excluding taxes, for each CD is 10.20.

    Step-by-step explanation:

    Given:

    Cost of first 5 CDs, C_1 = 3.00

    Cost of each additional CD = 15.00

    Now, cost of 10 additional CDs is the product of cost of one CD and total number of additional CDs. Therefore,

    Cost of 10 additional CDs is, C_2=15.00\times 10=150.00

    Now, total CDs purchased by Jana are, N=5+10=15

    Total cost of the 15 CDs purchased is given as:

    C_T=C_1+C_2=3.00+150.00=153.00

    Now, average price, excluding taxes, for each CD is given as:

    \textrm{Average price}=\frac{\textrm{Total cost of purchase}}{\textrm{Total number of CDs purchased}}\\\\\textrm{Average price}=\frac{C_T}{N}=\frac{153.00}{15}=10.20

    Therefore, the average price, excluding taxes, for each CD is 10.20.
