Answer:
7 CDs has been purchased.
Step-by-step explanation:
Given,
For the first CD, cost = $ 14.00,
Let x be the additional number of CD purchased by Maria,
That is, total purchased CD = x + 1,
Now, for each additional CD, cost = $ 12.00,
So, the cost of x additional CD's = 12x dollars,
And, the total amount of the CDs = (14 + 12x) dollars
According to the question,
Total cost = $ 86.00
⇒ 14 + 12x = 86
⇒ 12x = 86 - 14 = 72
⇒ x = = 6
Hence, the total number of CDs purchased = 6 + 1 = 7.

<h3>How to determine the best option to choose?</h3>The complete question is added as an attachment
From the complete question, the probability in part D is
Probability = 33.5%
The options to choose one from are:
- Option 1: He can accept the tie, and the game is over.
- Option 2: He can make one more throw. Jake wins if he earns at least 30 points on the throw, but he loses if he earns less than 30 points.
The calculated probability is less than 0.5.
This means that Jake is more likely to lose than win
So, the best option for Jake is option (A) walk away
Hence, the option which makes more sense for Jake to choose is option (1) He can accept the tie, and the game is over.
