The answer is 3.7 when rounded
Set R(x) equal to C(x). Solve the resulting equation for x, paying attention to the domain of C(x):
Solve 200x-2x^2 = -x^2 + 25x + 31000 for x greater than or equal to zero but less than or equal to x. That means you must reject any solution outside of this domain.
Rearrange all of these terms on the left side of your equation and place zero on the right side. Next, rearrange all of the terms on the left side in descending order by powers of x. Next, solve the resulting quadratic equation. Make certain to reject any x that does not fall within [0,100].
Answer:
28
Step-by-step explanation:
To begin, lets make an equation out of this problem,
x/32 = 7/8
Then, let's solve for the variable x or AKA the missing value
x/32 x 32 = 7/8 x 32
x = 28
So, there is the answer, the missing value is 28

My first impulse is to say you don't provide enough info with which to solve this problem. We need to know how many inches in the model correspond to 1 foot in the actual plane (that is, the scale factor). What is the scale factor here?
