Answer:
Step-by-step explanation:
4x10=40
7x10=70
6x10=60
10x10=100
8x10=80
4x14=56
5x16=80
40+70+60+100+80+56+80= $486

Step-by-step explanation:
The given equation is

The graph of the left hand side of this equation is

This quadratic graph has its vertex at (0,2) and turns upside down.
The right hand side of the equation is

This quadratic graph opens upwards and has its vertex at (0,-8).
The two graphs intersects at two points , which are (-2,0) and (2,0).
Answer:
This is the farthest I could go in solving the equation. Is there anymore information about the problem? Unless you are looking for n which it would seem n would equal 10.
