Answer:

b) The cost of 11 T-shirts during bargain days is $85.75
Step-by-step explanation:
We are given the following information in the question:
Discounted cost of one T-shirt = $8.25
Additional off on coupon = $5.00
Let t be the number of T-shirts bought during the bargain days.
a) Then, the price of t T-shirts with the discount applied will be given by the function:

b) Price during Bargain Days for 11 shirts
We put t = 11 in the above function:

Thus, the cost of 11 T-shirts during bargain days is $85.75
Is there a picture that suppose to come with this
Step-by-step explanation:
Domain of a rational function is everywhere except where we set vertical asymptotes. or removable discontinues
Here, we have

First, notice we have x in both the numerator and denomiator so we have a removable discounties at x.
Since, we don't want x to be 0,
We have a removable discontinuity at x=0
Now, we have

We don't want the denomiator be zero because we can't divide by zero.
so


So our domain is
All Real Numbers except-2 and 0.
The vertical asymptors is x=-2.
To find the horinzontal asymptote, notice how the numerator and denomator have the same degree. So this mean we will have a horinzontal asymptoe of
The leading coeffixent of the numerator/ the leading coefficent of the denomiator.
So that becomes

So we have a horinzontal asymptofe of 2
Yes, three is greater than -2
5. The blue one is y >= 5x - 7
and green is y >= -0.65x + 3
6. y <= (4/5)x
y >= -(5/4)x
