Percentage Error

9*(x-1)=2x-7
First get rid of your parenthesis by distributing.
9x-9=2x-7
Then all you have to do is isolate the variable
9x=2x+2
7x=2
so x= 2/7

He cost, in millions of dollars, of building a three-story high school in new york state was estimated to be c(x) = 2.1 + 0.12x

ratelena [41]

Given cost function is

c(x) = $2.1 + 0.12x - 0.0001x^2$ (20 ≤ x ≤ 400)

where x is the number of thousands of square feet

total revenue will be $0.2 million dollars per thousand square feet

Revenue is 0.2 millions per thousand square feet. we know x is the number of thousand of square feet

So R(x) = 0.2x

We know Profit = Revenue - Cost

P(x) = R(x) - C(x)

$P(x) = 0.2x - (2.1 + 0.12x - 0.0001x^2)$

$P(x) = 0.2x - 2.1 - 0.12x + 0.0001x^2)$

combine like terms

$P(x) =-2.1 + 0.08x + 0.0001x^2$

Profit function is

$P(x) =0.0001x^2 + 0.08x - 2.1$
