Answer:
First find what the sale price of the CD is. 30% off means the CD is selling for 70% of the original cost ( 100%-30% = 70%)
Multiply the original cost by 70%:
17.00 x 0.70 = $11.90 ( sale price)
Now you need to multiply the sale price by the tax percentage to find the amount of tax:
11.90 x 0.08 = 0.95 ( tax)
Now add the sale price and the tax for the total cost:
11.90 + 0.95 = $12.85

Recall that the characteristic polynomial of a 2x2 matrix
is
but
and
, so the characteristic polynomial for
is
We're given that the trace is 15 and determinant is 50, so the characteristic polynomial for the matrix in question is
and the eigenvalues are those
for which the characteristic polynomial evaluates to 0.
