The <span>principle that helps us to determine the total number of outcomes in a sample space is the counting principle.
</span>The Fundamental Counting Principle: If there are “a” ways for one event
to happen, and “b” ways for a second event to happen, then there are “a
* b” ways for both events to happen.
Hey there!
To start, first set up your expression like this:
(5x+17)-(3x-4)
You must set up your expression like this since in subtraction, order matters and the problem asks for the difference between the first plant and the second plant, respectively, meaning you must follow in this order.
Now, simplify:
(5x+17)-(3x-4)
(5x+17)+(-3x+4)
2x+21
Therefore, the difference the two companies would be 2x+21.
