Answer:
My total savings was = $58.33
Step-by-step explanation:
Given:
12% of my savings was = $7.00
To find my total savings.
Solution:
Let the total savings in dollars be = ![x](https://tex.z-dn.net/?f=x)
12% of the total savings will be = ![12\%\ of\ x](https://tex.z-dn.net/?f=12%5C%25%5C%20of%5C%20x)
12% of my savings was = $7.00
So, we have:
![12\%\ of\ x=7](https://tex.z-dn.net/?f=12%5C%25%5C%20of%5C%20x%3D7)
![0.12x=7](https://tex.z-dn.net/?f=0.12x%3D7)
Solving for
to get my total savings.
Dividing both sides by 0.12
![\frac{0.12x}{0.12}=\frac{7}{0.12}](https://tex.z-dn.net/?f=%5Cfrac%7B0.12x%7D%7B0.12%7D%3D%5Cfrac%7B7%7D%7B0.12%7D)
∴ ![x=58.33](https://tex.z-dn.net/?f=x%3D58.33)
Thus, my total savings was = $58.33
The denominator can't equal 0.
![11(x-7) \not= 0 \\ x-7 \not=0 \\ x \not= 7 \\ \\ \\ \frac{(2x+1)(x-7)}{11(x-7)}=\frac{2x+1}{11} \\ \\ (2x+1)(x-7) \cdot 11= 11(x-7) \cdot (2x+1) \\ 11(2x+1)(x-7)=11(2x+1)(x-7) \\ \\ x \in R \setminus \{7 \}](https://tex.z-dn.net/?f=11%28x-7%29%20%5Cnot%3D%200%20%5C%5C%20x-7%20%5Cnot%3D0%20%5C%5C%20x%20%5Cnot%3D%207%20%5C%5C%20%5C%5C%20%5C%5C%20%5Cfrac%7B%282x%2B1%29%28x-7%29%7D%7B11%28x-7%29%7D%3D%5Cfrac%7B2x%2B1%7D%7B11%7D%20%5C%5C%20%5C%5C%0A%282x%2B1%29%28x-7%29%20%5Ccdot%2011%3D%2011%28x-7%29%20%5Ccdot%20%282x%2B1%29%20%5C%5C%0A11%282x%2B1%29%28x-7%29%3D11%282x%2B1%29%28x-7%29%20%5C%5C%20%5C%5C%0Ax%20%5Cin%20R%20%5Csetminus%20%5C%7B7%20%5C%7D)
The answer is D.

Answer:
<h3>100 tickets</h3>
Step-by-step explanation:
Probability of winning = amount of tickets purchased/Total number of tickets
20% = 20/total number of tickets
20/100 = 20/total number of tickets
cross multiply
20 * total number of tickets = 20 * 100
20 * total number of tickets = 100
total number of tickets sold = 100 tickets
