Okay well the starting is 28 dollars, right. But since there is a 20 percent discount, you have to turn 20% to a decimal. That means moving the decimal sign twice to the left to make it .20. From the it would be .20*28, that should equal 5.6. Now, that 5.6 is the amount you have to take away, it is the price of the sale. From then, you subtract which is 28-5.6 which should be 22.4. From that 22.4 you now take away two dollars and then it should be 22.4-2 which should be 20.4. Now that is your answer, 20.4.

Given:
Right Rectangular Prism.
It has its length, width, and height.
Surface area of a right rectangular prism has this formula:
SA = 2 (wl + hl + hw)
Volume of a right rectangular prism has this formula
V = whl
Formula of Surface Area is different from Volume.
Surface
area measures the area the whole rectangular prism surface. It computes
for the area of all 6 faces that a right rectangular prism has.
Volume measures the area within the rectangular prism. It is the space that is enclosed within the rectangular prism.
Since you’re multiplying n^-6 and n^3, you can add the exponents: -6+3 = -3
n^-6 * n^3 = n^-3
If you need to finish without having a negative exponent in your answer, then remember a negative exponent means that factor is on the wrong side of the fraction.
n^-3 = n^-3 / 1 = 1/n^3
when the factor moves to the other side of the fraction, the side of the exponent changes.
