Answer:
The percentage of people going to the people in week 4 compared to week 1 decreased by 25%.
Step-by-step explanation:
Week 1: 1,040 people
Week 2: 105 fewer people
1040 - 105 = 935 people
Week 3: 135 more people
935 + 135 = 1070 people
Week 4: 290 fewer people
1070 - 290 = 780 people
So, there were 260 fewer people, going to the pool in those 4 weeks compared to week 1.
Now, we must find the percentage change.
x/100 = 780/1040
Cross multiply.
1040x = 78000
Divide both sides by 1040 to leave x by itself on one side.
x = 78000/1040
x = 75%
This means only 75% of the total people from week one were going to the pool in week four. Therefore, there was a 25% decrease in the number of people who went to the pool over these four weeks.

Answer:
B. & E.
Step-by-step explanation:
First, to find your slope, put your line into slope-intercept form.
Your slope is 
.
Now, you can find the y-intercept of your parallel line by plugging your given point and your slope into point-slope form.
Your y-intercept is 1.
If you notice, answer choice E is equivalent to one of our steps in converting it to point-slope form. Therefore, E is one of your answers.
The equation of your parallel line is:
B is also a correct answer.
If you put B into slope-intercept form, you get the following:
This, of course, is equivalent to the parallel line which we already found, so we know it is parallel.
