The cost of some office furniture after a 20% reduction was $3,520.00. what was the original price of the furniture, before the discount?

Step-by-step explanation:

Let the original price of furniture be $x.

Reduction in  price = 20%x =.20x.

Reduced price = x-.20x.

It is given reduced price is $3,520.00

So,

x-.20x=3,520.

0.80x= 3,520

Dividing both sides by .80

x=3,520÷.80

x=$4400.

The original price of furniture before discount is $4,400.

a.)the line for function b is steeper

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
