Answer:
513 turkey sandwiches were sold.
Step-by-step explanation:
Let's use
to represent turkey sandwiches and
to represent steak sandwiches.
= turkey sandwiches
= steak sandwiches
total sandwiches that were sold
dollars that were made

Now that we know what
(steak sandwiches) equals, we plug it in to an equation to find
.

Now, we subtract 5,550 from BOTH sides so we can get x by itself.

Next, we divide both sides by 2, so x is bare.


Since x represents turkey sandwiches, we have our answer: 513 turkey sandwiches were sold.
I hope this helps! :)
The number to which a base is raised to is called the _exponent_ This tells you how many times to multiply the base together.
Answer:
To answer items such as this, we directly substitute the a + 2 to the all the x's in the function such that,
f(a + 2) = (3 + a + 2) / (a + 2 - 3)
Simplifying the function generated above,
f(a + 2) = (5 + a) / (a - 1)
