<u><em></em></u>
- <u><em>Option A. 94</em></u>
Explanation:
The column of digits to the left (before the vertical line) contains the largest place-value digits.
Here is how you read the values:
- Third row: 80, 80, 81, 82, 85, 88, 89
Thus, the highest score received is 94.
Given:
The cost C (in dollars) to participate in a ski club is given by,
![\begin{gathered} C=85x+60 \\ (or) \\ x=\frac{C}{85}-\frac{12}{17} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20C%3D85x%2B60%20%5C%5C%20%28or%29%20%5C%5C%20x%3D%5Cfrac%7BC%7D%7B85%7D-%5Cfrac%7B12%7D%7B17%7D%20%5Cend%7Bgathered%7D)
Where x is the number of ski trips we take.
To find:
The number of ski trips when a total cost of $315 and $485 is spent.
Explanation:
Substituting C = 315 in the given equation we get,
![\begin{gathered} x=\frac{315}{85}-\frac{12}{17} \\ x=\frac{315-60}{85} \\ x=\frac{255}{85} \\ x=3\text{ ski trips} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%3D%5Cfrac%7B315%7D%7B85%7D-%5Cfrac%7B12%7D%7B17%7D%20%5C%5C%20x%3D%5Cfrac%7B315-60%7D%7B85%7D%20%5C%5C%20x%3D%5Cfrac%7B255%7D%7B85%7D%20%5C%5C%20x%3D3%5Ctext%7B%20ski%20trips%7D%20%5Cend%7Bgathered%7D)
Substituting C = 485 in the given equation we get,
![\begin{gathered} x=\frac{485}{85}-\frac{12}{17} \\ x=\frac{485-60}{85} \\ x=\frac{425}{85} \\ x=5\text{ ski trips} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%3D%5Cfrac%7B485%7D%7B85%7D-%5Cfrac%7B12%7D%7B17%7D%20%5C%5C%20x%3D%5Cfrac%7B485-60%7D%7B85%7D%20%5C%5C%20x%3D%5Cfrac%7B425%7D%7B85%7D%20%5C%5C%20x%3D5%5Ctext%7B%20ski%20trips%7D%20%5Cend%7Bgathered%7D)
Thus,
If we spend a total cost of $315, we can take 3 ski trips.
If we spend a total cost of $485, we can take 5 ski trips.
Final answer:
• If we spend a total cost of $315, we can take 3 ski trips.
,
• If we spend a total cost of $485, we can take 5 ski trips.
