None of the options give the same fees for a session of x hours.
Given,
x + 20/2 = 3x
when two tutoring services with different rate plans charge the same fees for a session of x hours.
<h3>What is arithmetic?</h3>
In mathematics, it deals with numbers of operations according to the statements.
x + 20/2 = 3x
x + 10 = 3x
A) x= 10
10 + 10 = 3*10
20 ≠ 30
B) x=4
4 + 10 = 3 * 4
14 ≠ 12
C) x= -14
-14 + 10 = 3 * -14
-4 ≠ 42
D) x=-17
- 17 + 10 = 3 * - 17
-7 ≠ -51
Here, none of the options give the same fees for a session of x hours.
Thus, none of the options give the same fees for a session of x hours.

To simplify the expression, we will use the following rules:
So, the given expression will be as follows:
So, the answer will be the second option
The total cost she needs is 11000 times 5 which is 55,000. so you do 5 times 5000 for her annual grant is 25000 and 900 times 5 is 4500. now you add 25000 plus 4500 is 29500. 29500 is what she has. 55,000 minus 29500 is 25,500. 25,500 is what she needs now. now she has a loan of 400 per year. 400 times 5 is 2,000. 25,000 minus 2,000 is 23,000. so the answer is that she needs to borrow 23,0000.
