The original selling price of a shirt was $45.
marissa [1.9K]

Given:

The original selling price of a shirt was $45.

In a sale, the shirt is reduced to $32.50.

To find:

The percentage reduction.

Solution:

We know that,

\text{Percentage reduction}=\dfrac{\text{Original value - Reduced value}}{\text{Original value}}\times 100

\text{Percentage reduction}=\dfrac{45-32.50}{45}\times 100

\text{Percentage reduction}=\dfrac{12.50}{45}\times 100

On further simplification, we get

\text{Percentage reduction}=\dfrac{1250}{45}

\text{Percentage reduction}=27.777778

\text{Percentage reduction}\approx 27.78

Therefore, the percentage reduction is 27.78%.

How would you write 1 - x^4 before you divide it by x - 1?
devlian [24]
Order your terms by the powers of exponents in decreasing order (as is the case with pure number division hundreds, tens, ones, tenths, etc, etc) as x^n, x^n-1 etc...

(-x^4+1)/(x-1)
-x^3 rem -x^3-1
-x^2 rem -x^2-1
-x     rem -x-1
-1     rem 0

(x-1)(-x^3-x^2-x-1)

(x-1)(-x^3-x-x^2-1)

(x-1)(-x(x^2+1)-1(x^2+1))

(x-1)(-x-1)(x^2+1)
