4(2n - 9) = 10n - 8
8n - 36 = 10n - 8
8n - 8n - 36 = 10n - 8n - 8
-36 = 2n - 8
-36 + 8 = 2n - 8 + 8
-28 = 2n
-28/2 = 2n/2
-14 = n
The answer is 6 and that’s after it’s rounded
The Median is the middle value.
Arrange the numbers in order from smallest to largest:
Seattle: 23.78 , 32.46, 40.30, 45.79, 49.42, 55.14
Since there is an even number, the median is found by adding the 2 middle numbers and dividing by 2.
Median for Seattle: 40.30 + 45.79 = 86.09 / 2 = 43.045
Now do the same for Las Vegas:
2.33, 3.72, 3.84, 4.11, 5.62, 8.79
Median for Las Vegas: 3.84 + 4.11 = 7.95 / 2 = 3.975
Difference: 43.045 - 3.975 = 39.07
The answer is B.
