Answer:
t = pn
Step-by-step explanation:
We are to find the relationship between total cost and the number of items.
First we would represent the relationship between total cost and number of items with variables
Let the total cost = t
and the number of items = n
Total cost t is proportional to the number n of items:
t ∝ n
t = kn
where k is constant
Since it is purchased at a constant price p, the constant of proportionality would be p. the k would be replaced with p
t = pn

Rigid mapping is used to illustrate rigid transformation.
The rigid mapping rules are:
- <em>(a) (x, y)->(y,x)
</em>
- <em>(c) (x, y)->(-y, x)
</em>
- <em>(d) (x, y)-> (-y +4, X-6)
</em>
- <em>(e) (x, y)->(x + 4, y-5)
</em>
- <em>(f) (x, y)->(x, x+y)
</em>

All transformations are rigid except dilation.
This is so, because dilation <em>changes the size </em>of the function that is being transformed, while others do not.
Dilations are represented by scale factors (<em>product or division</em>)
From the list of given options
<em>(b) (x, y)->(3x, y) and (c) (x,y)-> (3)</em> are non-rigid mapping because they represent dilations.
Hence, the rigid mapping rules are:
- <em>(a) (x, y)->(y,x)
</em>
- <em>(c) (x, y)->(-y, x)
</em>
- <em>(d) (x, y)-> (-y +4, X-6)
</em>
- <em>(e) (x, y)->(x + 4, y-5)
</em>
- <em>(f) (x, y)->(x, x+y)
</em>
