Step-by-step explanation:
<h3>
Answer: 700 dollars</h3>
================================================
Work Shown:
35% = 35/100 = 0.35
35% of 2000 = 0.35*2000 = 700
Since the card increased by 700 dollars, this means the card is now worth 2000+700 = 2700 dollars.
The answer is false.
There are only for operations for arithmetics.
Addition. Subtraction. Multiplication. Division.

Let
![L_1](https://tex.z-dn.net/?f=L_1)
denote the event that a student is a freshman,
![L_2](https://tex.z-dn.net/?f=L_2)
a sophomore,
![L_3](https://tex.z-dn.net/?f=L_3)
a junior, and
![L_4](https://tex.z-dn.net/?f=L_4)
a senior.
Let
![E](https://tex.z-dn.net/?f=E)
denote the event that a student majors in engineering. By the law of total probability,
![\mathbb P(E)=\mathbb P(E\cap L_1)+\mathbb P(E\cap L_2)+\mathbb P(E\cap L_3)+\mathbb P(E\cap L_4)](https://tex.z-dn.net/?f=%5Cmathbb%20P%28E%29%3D%5Cmathbb%20P%28E%5Ccap%20L_1%29%2B%5Cmathbb%20P%28E%5Ccap%20L_2%29%2B%5Cmathbb%20P%28E%5Ccap%20L_3%29%2B%5Cmathbb%20P%28E%5Ccap%20L_4%29)
By the definition of conditional probability, we can expand each of these intersection probabilities to get
![\mathbb P(E)=\mathbb P(E\mid L_1)\mathbb P(L_1)+\mathbb P(E\mid L_2)\mathbb P(L_2)+\mathbb P(E\mid L_3)\mathbb P(L_3)+\mathbb P(E\mid L_4)\mathbb P(L_4)](https://tex.z-dn.net/?f=%5Cmathbb%20P%28E%29%3D%5Cmathbb%20P%28E%5Cmid%20L_1%29%5Cmathbb%20P%28L_1%29%2B%5Cmathbb%20P%28E%5Cmid%20L_2%29%5Cmathbb%20P%28L_2%29%2B%5Cmathbb%20P%28E%5Cmid%20L_3%29%5Cmathbb%20P%28L_3%29%2B%5Cmathbb%20P%28E%5Cmid%20L_4%29%5Cmathbb%20P%28L_4%29)
