Answer:
$105
Step-by-step explanation:
$15 for one case of snicker bars. Since it's $30 for 2. He needs 140 so 140 divided by 20(which is in one case) = 7. So he needs 7 cases to have 140 snicker bars. Well, if each case itself is $15 and we need 7 cases. 7 times 15= 105. It's going to cost him $105 to fill that vending machine.
Given:
To find:
The values of x.
Solution:
We have,
(Distributive property)
(Combining like terms)
Add 28 on both sides.
Subtract 10x from both sides.
Divide both sides by 14.
Therefore, the values of x are all real numbers less than 2, i.e., x<2 .

For the first question:
C.) $240
For the 4 year plan you take $332 a month and multiply by 12 to get the annual value of $3,984. Then multiply that by 4 to get $15,936.
For the 3 year plan take $436×12 to get $5,232, then multiply that by 3 years and you get $15,696.
Finally, to find the difference do $15,936-$15,696 and you get $240.
For the second question:
The new value is between 10 and 12.
Mean refers to the average between all the data paints, while the mean absolute deveiation is the average distance between the data point and the mean. So if the value was 11, for example, the mean, or average would increase from 10, while the MAD would only be 1, decreasing it.
