Given coordinates of the triangle RST are R(2,1), S(2,-2) and T(-1,-1).
Center of center of dilation is (2,-2).
Because center of dilation is (2,-2) so the coordinates of dilated image S(2,-2) would stay same.
Now, we need to apply rule for dilation with the scale factor 5/3.
Each of R(2,1), and T(-1,-1) would be and R' and T' would be in ratio 5/3.
We will extend RS to 5 units and TS also 5 units.
The new resulting image would be dilated triangle by a scale factor 5/3.

Answer:
800
Step-by-step explanation:
Given: The selling price of bed is 2400.
Discount offered is 25%
Lets assume the cost of bed be "x"
Discount offered on the cost price of bed=
∴ Discount offered on the cost price of bed= 0.25x
We know the selling price of bed after discount provided.
Finding the cost price of the bed.
⇒
⇒
cross multiplying both side.
∴
∴ Cost price of the bed is 3200.
We know selling price of the bed is 2400.
Now, finding the saving.
Saving on the price of bed= Cost price- selling price
Saving=
Hence, saving on the purchase of the bed is 800.
