The following section is a statement from the rental agreement Tim signed when he rented his car this past weekend.
2 answers:
Option D is the correct answer.
Explanation:
As given, if the car is returned with a fuel level below the mentioned level, it will be completely re-fueled and the cost will be added to Tim's total bill.
As, the fuel needed to fill the car is 11.75 gallons and cost of a gallon is $4.50, so total cost becomes
=
And the cost of re fueling is $5, so total cost becomes = ≈ $57.88
So, total cost is $57.88 (option D)

Answer:
Mean : 95
Median : 85
Mode : 90
Part B : Impossible
Step-by-step explanation:
We can make an equation to find the mean using the first 5 history test scores.
So a 95 would be needed to have a mean of 85.
Next, the median.
First, we sort the first 5 history scores from least to greatest.
We get 75, 75, 80, 90, 95.
Since, 80 is the middle value, it will be used in the calculation of the median.
We can make an equation with this.
So a score a 85 would be needed to have a median of 82.5
Thirdly, the mode.
Since 90 is already in the set once, we can just have Maliah score another 90 to make 90 the mode (with the exception of 75 of course).
Finally, Part B.
We can use the equation we had for the first mean calculation but change 85 to 90.
So Maliah would need a score of 125 to make her mean score 90, but since the range is only from 0-100, it is impossible.
