Answer:
a)

b)

Step-by-step explanation:
a)
Assume that r is a regular price before discount and tax
Including discount, we substract 5 from r. We get (r-5).
Then, we include tax by adding 5% value of (r-5)
Including a tax we may realize by multiplying initial value (r-5) by 1.05, where an ending .05 is percentage value of a tax
b)
in a formula
we substitute r=15.50 and calculate the value on the right side of the sign "=".
You solve it too, using a calculator.
If you push the following buttons:
1 5 . 5 0 - 5 = + 5 %
you should get a result 11.025, after approximation to the 2 digits after comma there is 11.03
The Jacobian for this transformation is

with determinant
, hence the area element becomes

Then the integral becomes

where
is the unit circle,

so that

Now you could evaluate the integral as-is, but it's really much easier to do if we convert to polar coordinates.

Then

Answer:
The "solutions" to the Quadratic Equation are where it is equal to zero. They are also called "roots", or sometimes "zeros" There are usually 2 solutions (as shown in this graph). And there are a few different ways to find the solutions: We can Factor the Quadratic (find what to multiply to make the Quadratic Equation)
