It would be: 213500 * 18/100
213500 * 0.18 = $38430
So, option D is your answer.
Hope this helps!
-13k + 7k - 4 = 23 + 16k - 2
-13k + 7k - 16k = 23 - 2 + 4
-22k = 25
k = 25/-22
The variable the researchers intentionally varied in the experiment is time and the units of the variable is mins.
<h3>What is an independent variable?</h3>
The independent variable is the variable that the researcher varies or changes or manipulates in the course of the experiment. The independent variable usually have a direct effect on the dependent variable.
With the passage of time, the level of concentration increases. This means that time is the independent variable and concentration is the dependent variable.

The solution to the inequalities 3x + 5 < 6x + 8 and 4x + 3 < 7x + 5 is x > -1 and x > -2/3 respectively
<h3>Inequality</h3>
Inequality signs are;
- Greater than >
- Less than <
- Equal to =
- Less than equal to ≤
- Greater than equal to ≥
3x + 5 < 6x + 8
3x - 6x < 8 - 5
-3x < 3
x > 3/-3
The inequality sign is flipped from < to greater than because of the division with negative value.
x > -1
2. 4x + 3 < 7x + 5
4x - 7x < 5 - 3
-3x < 2
The inequality sign is flipped from < to greater than because of the division with negative value.
x > -2/3
