A rare first-edition book is currently priced at $200. After one year, the price of the book is anticipated to be 1.15 times the
current price of the book. Then, one year after that, the price of the book is anticipated to be 1.15 times the price of the book the previous year. If this pattern continues, which of the following graphs represents the price of the book over time?

Answer:
Part a) The graph in the attached figure (see the explanation)
Pat b) see the explanation
Step-by-step explanation:
Part a) Write and graph a system of linear inequalities that represents this situation
Let
x ----> the number of shirts you can buy
y ----> the number of pants you can buy
we know that
The word "at most" is the same that " less than or equal to"
The word "at least" is the same that " greater than or equal to"
so
----> inequality A
The amount you have to spend minus the number of shirts multiplied by its price minus the number of pants multiplied by its price must be greater than or equal to $20
Rewrite
----> inequality B
using a graphing tool
see the attached figure
Part b) How many shirts and pairs of pants can you buy at the store?
The solution of the system of inequalities is the shaded area
The solution is all whole numbers included in the shaded area
Example
(0,5),(3,3),(6,0), (3,2),...
