Answer:
The credit card purchase price of the same item is $87.5
Step-by-step explanation:
Here, we are interested in calculating the credit-card purchase price of an item if we are given the cash price
Since there is a 4% discount on the cash; the percentage paid will be 100-4% = 96%
So what we are saying is that, it is 96% of the credit cash purchase that was paid as cash;
Let the credit card purchase be $x
96% of x = 84
96/100 * x = 84
96x = 100 * 84
x = 8400/96
x = 87.5
Thus, the credit card purchase price of the same item is $87.5
Ok screw it, I went and watched a video on it
You calculate MAD by working out the absolute value that each data point is away from the mean
To do so, subtract each point from the mean, and then you don't care if the result is positive or negative, you just write it as positive
So
4 - 7 = -3, deviation is 3
4 - 7 = -3, deviation is 3
4 - 7 = -3, deviation is 3
5 - 7 = -2, deviation is 2
8 - 7 = 1, deviation is 1
9 - 7 = 2, deviation is 2
9 - 7 = 2, deviation is 2
9 - 7 = 2, deviation is 2
9 - 7 = 2, deviation is 2
9 - 7 = 2, deviation is 2
Now, you add up all the deviations, and divide them by the number of points of data you have, so
(3 + 3 + 3 + 2 + 1 + 2 + 2 + 2 + 2 + 2)/10, or simply
22/10
So the MAD is 2.2

The next number is half of the previous number so the answer is D
Given:
53 gal 1 qt + 12 gal 3 qt + 82 gal 1 qt
To find:
The sum of the given expression.
Solution:
Let us first add gallons:
53 gal + 12 gal + 82 gal = 147 gal
Now, add quarts.
1 qt + 3 qt + 1 qt = 5 qt
We know that,
4 quarts = 1 gallon
So add 1 gallon to 147 gal.
147 gal + 5 qt = 147 gal + 4 qt + 1 qt
= 147 gal + 1 gal + 1 qt
= 148 gal + 1 qt
= 148 gal 1 qt
Therefore, 53 gal 1 qt + 12 gal 3 qt + 82 gal 1 qt = 148 gal 1 qt
