9. The seventh-grade class is raising money to have a class trip at the end of the year. They
began the year with $1,500. Now they have
$1,650 in the account.
a. What is the percent of increase for the
money the class has raised?
b. Make Sense and Persevere The class
figured out that if the percent increase is
99% from the beginning of the year, the
class will have enough money for every
student to go on the field trip. How
much money will the class need to raise
for every student to go.

Can someone help I am so bad at math

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

i think it is 18

yes it represnts a functio, their are not 2 of the same numbers on the both sides
