im pretty sure C. 3(-64-8) + 25 will give you a positive value
Let the no. of stars one can expect to see at Bryce Canyon be x.
Given that : No. of stars visible in the night sky = 2000
Also, given that, it is 4/15 of x.
Now, we have

∴ You can expect to see 7,500 stars at Bryce Canyon.

The first thing we are going to do for this case is define variables.
We have then:
x: Amount of soybean meal
320 - x: quantity of cornmeal
We now write the equation that models the problem:

Rewriting we have:

From here, we clear x:

Then, the amount of Soybean meal is:

The amount of cornmeal is:
