P-.15p this is the expression for cost after discount
and its just .15p for just the discount
We'll use the notation
for the principal value and
for all the values:

Part I


Part II. In our range we can write


Part III.

Part IV.


A. Noncolinear
ABE although they are in the same side, but they don't lie on the same line.
so its a noncolinear.

Answer:
-2018
Step-by-step explanation:
The n-th term is ...
an = a1 +d(n -1)
So, the given terms are ...
-53 = a1 +12d
-128 = a1 +37d
Subtracting the first from the second gives ...
(a1 +37d) -(a1 +12d) = (-128) -(-53)
25d = -75
d = -3
The 668th term will be ...
a668 = a1 +d(668 -1) = a1 +667d = (a1 +37d) +630d
a668 = -128 +630(-3) = -128 -1890 . . . . substitute for a38
a668 = -2018
