The number of computers a certain computer store sold since 2005 can be modeled by
the function N (t) = 5t + 106 and the price per computer can be modeled by
P(t) = 13t? – 25t + 600, where t is the number of years since 2005.
According to this model, what is the total amount of revenue generated by the
computer store's sales in 2011?
Your answer should be a specific dollar amount.

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial

c > -10.55

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
