Answer:

Step-by-step explanation:
<u>Given:</u>
Percentage of Tickets sold at a water park - 68%
The Number of Tickets if the park sold in all - 50
<u>To </u><u>Find:</u>
The Number of child tickets the park sold.
<u>Solution:</u>
We know that 68% equals to 68/100.
Step 1: Multiply 68/100 by 50 which is the number of tickets the park sold :-

<u>Note</u>:The Simplified form of 68/100 * 50 would be the answer to this question.
Step 2: <u>Cancel One zero of 50 and one zero of 100,That is</u>:-

<em>Results to,</em>

Step 3: <u>Cancel 5 and 10, That is</u>:-

<em>Results to,</em>


Step 4: <u>Cancel 68 and 2, That is</u>:-

<em>Results to,</em>


34 is the result.
Hence,

Option A: z + 1
Option B: 6 + w
Option D: 
Solution:
Let us first define the polynomial.
A polynomial can have constants, variables, exponents and fractional coefficients.
A polynomial cannot have negative exponents, fractional exponents and never divided by a variable.
<u>To find which expressions are polynomial:</u>
Option A: z + 1
By the definition, z + 1 is a polynomial.
It is polynomial.
Option B: 6 + w
By the definition, 6 + w is a polynomial.
It is polynomial.
Option C: ![y^{2}-\sqrt[3]{y}+4](https://tex.z-dn.net/?f=y%5E%7B2%7D-%5Csqrt%5B3%5D%7By%7D%2B4)
![y^{2}-\sqrt[3]{y}+4=y^{2}-{y}^{1/3}+4](https://tex.z-dn.net/?f=y%5E%7B2%7D-%5Csqrt%5B3%5D%7By%7D%2B4%3Dy%5E%7B2%7D-%7By%7D%5E%7B1%2F3%7D%2B4)
Here, y have fractional exponent.
So, it is not a polynomial.
Option D: 
By the definition,
is a polynomial.
It is polynomial.
Hence z + 1, 6 +w and
are polynomials.
I think it's C, I could be wrong though
