100% - 30% = 70%
The shirt is selling for 70% of the original price.
Multiply the original price by 70%
26.98 x 0.70 = 18.89
The sale price is $18.89

This is a question about the composition of functions and how to get a domain function.
Given
and
.
We will form (b o a)(x) and then determine the domain.
<u>Step-1</u>

Replace each appearance of x in b(x) with
.

Thus, 
<u>Step-2</u>
To be defined, the value under the radical sign must not be negative. Therefore, the domain of
are processed as follows.

Both sides added by 3.

Both sides divided by 3.

Thus, the domain of
is

Keywords: composition of function, if a(x) = 3x + 1, and, b(x) = √(x-4), what is the domain of, (b o a)(x), b(a(x)), defined, the value, under the radical sign, must not be negative,
Use the equation
For A. The problem would be set up like so
5 _ -1
--------
4 _ -2
Start by subtracting 5 minus -1 which is 6 because minus a negative becomes a positive then subtract 4 minus -2 which is 6, remember minus a negative becomes a positive, then divide 6/6 to get 1
For B.
-5 _ -0
----------
3 _ -1
Again subtract -5 by -0 which no matter what will be -5. Then make -1 positive because it's a subtracted negative so it becomes 3+1 which gives you 4. Your answer is -5/4

There are 138 female patients in the hospital.
<h3>Solving word problems involving ratios.</h3>
The solution to the word problem involving ratios in the given problem can be determined as follows.
From the given information:
The total number of people in the hospital = male + female
= 184 + x(unknown)
- If the ratio of male to female is 4: 3.
- The total ratio is 4+3 = 7
The ratio of males in the hospital is:


x = 322
The number of female patients in the hospital can now be computed as:

= 138 female patients
Check:
The total number of people in the hospital is:
= 184 + 138
= 322 patients
