_____
There are all kinds of ways this might make sense, but none of them are supported by the information given in the problem statement.
Answer:
The correct option is:
100 + 0.8(x - 100) = 250
Step-by-step explanation:
We are given that:
We know that a department store gives 20 % off the portion of the bill that is over 100 dollars.
Total bill is 250 and x is the amount of money she would have spent without the promotion.
The cost to which the discount applies is 0.8 ( x - 100 ).
<em>Finally the equation we get is 100 + 0.8 (x - 100) = 250.</em>
Take 184m and times that by 6.5 and you will receive 1,196

Answer: 32</h3>
Explanation:
If a set has n items inside it, then there will be 2^n different subsets. This includes the original set itself (since any set is a subset of itself).
Here we have n = 5 items in the given set, so there are 2^5 = 32 different subsets.
For more information, I recommend looking up the term "power set".
