The question doesn't make a lot of sense, but I think the answer is $0.25, because In the equation b=0.25t, each text costs 25 cents
3.56 +/- 0.011 = ( 3.549, 3.571). This is the answer.

Answer:
First option: 
Step-by-step explanation:
Given the quadratic equation 
, you need to factor it.
To do this, you need to find two number that when you add them you get 11 and when you multply them you get 24. These numbers are: 8 and 3.
Therefore, knowing this, you can factor the quadratic equation:
Then, is equivalent to the graph of the equation , which matches with the first option.
11, 12, 15, 16, 20, 20, 25
Mean: 17
The range is 25-11 = 14 (the numbers in bold)
The interquartile range is 20-12=8 (the numbers underlined)
The mean absolute deviation is: 4; this is found by finding how far each number is from 17 (mean): 6,5,2,1,3,3,8 (28) and dividing by 7.
Part B:
The prices vary by no more that $14 (range).
<span>The middle half of the prices vary by no more than $8 (IQR).
</span>
<span>The admission prices differ from the mean price by an average of $4 (MAD).</span>
