Solve this problem by setting up a proportion to model the number of boys to the total number of students than the class:

80/100=20/x

Now, cross multiply:

80x=2000

Then, divide 2000 by 80 to solve for x:

x=25

25 is the total number students in the class.

Hope this help

**Answer:**

y = x

**Step-by-step explanation:**

Since the x-values and y-values remain the same all throughout the chart, it's in a 1 to 1 relationship.

That just means the numbers will ALWAYS EQUAL each other.

Hence, y = x

-8x+2. (4x+6)@=12

-8x+8x+12=12

12=12

0=0

The correct answer is D. 100%

Each tick counts as 8 so the beginning of the plot would be at 28 which is only 2 from 30 and everything else is on the plot is greater than 30 so the answer would have to be D since 75% would be too little coverage of the plot
