PolarNik [594]

Answer:

Step-by-step explanation:

First, replace f(x) with y . ...

Replace every x with a y and replace every y with an x .

Solve the equation from Step 2 for y . ...

Replace y with f−1(x) f − 1 ( x ) . ...

Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.

After a 35% discount, a book costs $11.21, what is the normal<br> undiscounted price of the book?

9966 [12]

Answer:

The normal undiscounted price of the book is $17.25.

Step-by-step explanation:

This question can be solved using a rule of three.

After a 35% discount, a book costs $11.21

This means that $11.21 is 100-35 = 65% = 0.65 of the original price x.

How much is x, which is 100% = 1?

$11.21 - 0.65

$x - 1

$0.65x = 11.21$

$x = \frac{11.21}{0.65}$

$x = 17.25$

The normal undiscounted price of the book is $17.25.
