Answer:
f(x)=x^2+9x-10
Step-by-step explanation:
<u>Standard Form of Quadratic Function</u>
The standard form of a quadratic function is:
where a,b, and c are constants.
The factored form of a quadratic equation is:
Where 
and 
are the roots or zeros of f, and a is constant.
We know the zeros of the function are 1 and -10. The function is:
Operating:
Joining like terms:
Since we are not given any more restrictions, we can choose the value of a=1, thus. the required function is:
4x + 160y = 120
and
1x + 240y = 80
that will be be the equations. if we multiply the bottom equation by 4 we get:
4x + 960y = 320
now subtract one equation from another:
4x + 160y = 120
-(4x + 960y = 320)
and get:
-800y = -200
y = $0.25
now plug this into one equation
x +240(.25) = 80
x + 60 = 80
x = $20
so $20 per day and $0.25 per mile
