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.

Answer:The number of days it will take to sell the same amount of cookies is 3 and the number of tubs that will be sold is 27
Step-by-step explanation:
Let x represent the number of days it will take either of them to sell the same number of tubs.
Let y represent the total number of tubs that that Joseph will sell in x days.
Let z represent the total number of tubs that that Dwayne will sell in x days.
Joseph has already sold 3 tubs. If Joseph starts selling 8 tubs per day, it means that in x days, the number of tubs that he will sell will be
y = 8x + 3
Dwayne hasn't sold any yet. If Dwayne begins selling 9 tubs per day, it means that in x days, the number of tubs that he will sell will be
z = 9x
To determine the number of days it will take to sell the same amount of cookies, we will equate y to z. It becomes
8x + 3 = 9x
9x - 8x = 3
x = 3
The number of tubs that each will sell will be 9x = 9×3 = 27
When you say either, you add both A and B
0.3+0.4=0.7
Your answer is 0.70 which means 70%
