Answer:
Every book is 8 dollars but you have to subtract 10, so like this:
Step-by-step explanation:
p(x) = 8x - 10 Lets say you sell 2 books
p(2) = 8(2) - 10
p(2) = 16 - 10
p(2) = 6 You would make 6 dollars.

Step-by-step explanation:
The system of equations is;
-12x-13y +13z =15
7x-10y-3z = 11
7x+14y +5z = -5
