If the price went down $5 per day for four days straight, then it would have went down $20 total after the four days.
Answer: FIrst option, Fourth option and Fifth option.
Step-by-step explanation:
First it is important to know the definition of "Dilation".
A Dilation is defined as a transformation in which the Image (which is the figure obtained after the transformation) and the Pre-Image (this is the original figure, before the transformations) have the same shape, but their sizes are different.
If the length of CD is dilated with a scale factor of "n" and it is centered at the origin, the length C'D' will be:

Therefore, knowing this, you can determine that:
1. If
, you get:

2. If
, then the length of C'D' is:

3. If
, then:

4. If
, then, you get that the lenght of C'D' is:

5. If
, the length of C'D' is the following:

The final answer should be -49/168.
D. works because if you work it out that means 2n=140 and then divide by 2 which means n=70 and the other number is 71
2000/200 is 100!! so it will be 100
