A sofa set was bought for rs.9000and sold at a loss of 25 percent . what was the selling price ? chapter in maths is comparing quantities
need answer fast pls help . will give full stars !

selling price was 6750

Step-by-step explanation:

9000 x 0.25 = 2250

9000 - 2250 = 6750

=rs. 6750

Step-by-step explanation:

marked price=     9000   =       100%

selling price=          ?        =       75%

loss=                        ?        =        25%

as he made a loss it means that he sold the sofa for a lower price hence the selling price will be lower than the marked price.

selling price = if  100% = 9000

        what about    75%?

   75% x 9000

        100%

=rs.6750            

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
