Rochelle works part-time at the college museum, which pays her at a rate of $10 per hour. She also makes small bracelets that sh
e sells for $5 a piece. She needs to earn at least $200 a week to cover her expenses. Let x represent the number of hours that Rochelle works at the museum, and let y represent the number of bracelets she sells. One of the graphs below shows the inequality that represents this situation, with its solution region shaded.

Let RS be denoted as y.
Given that T is the midpoint of RS, this results in RT = TS =
And W acting as the midpoint of RT, leads to
thus RW = WT =
Given that Z is the midpoint of WS.
Meaning WZ = ZS =
Consequently, TZ = TS - ZS =
However, TZ is defined as x.
Thus,
y = 8x = RS.
A) Length of RW =
B) Length of WZ =
C) Length of RS = y = 8x
D) Length of ZS = WZ = 3x.
