Well first you would start by setting up with a proportion.
In total, the girls paid $54+$22= $76
Thus 1 sister contributed $54/$76=x/100
The other sister contributed $22/$76=x/76
For each proportion, cross-multiply and simplify to get the percentage. The percentage will be the x
To find a percent, you use this simple formula:
5000/62000 = x/100
In this case, x is going to be your percent of commission.
So, to find this, you first divide 5000 by 62000, which is about equal to 0.08.
Now your equation looks like this:
0.08 = x/100
Next, you multiply both sides by 100 to reverse the operation. Now, your equation will look like this:
8 = x
So, the answer is 8%.

Answer:
B. The graph flips over the x-axis
Step-by-step explanation:
When you plot the coordinate pair (x, y), you plot the point 'y' units above the x-axis. If you change the sign of that (multiply the function by -1), then the point becomes (x, -y), and is plotted 'y' units below the x-axis.
The graph flips over the x-axis.

Attached is an example of a function with its original graph (red) and the graph after being multiplied by -1 (blue). The blue graph is a reflection of the red graph across the x-axis.
I don't think a decimal number could have 2 decimal points.
