= -315
So, the answer is -315.
Answer:
25 rounds
Step-by-step explanation:
Let
x -----> the number of rounds of golf
y ---> total charges to play
The linear equation in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the slope or unit rate
b is the y-intercept or initial value
<em>Membership</em>
----> equation A
The slope is m=$35 per round
The y-intercept b=$500 (annual membership fee)
<em>Non-Membership</em>
----> equation B
The slope is m=$55 per round
The y-intercept b=$0
Equate equation A and equation B
![55x=35x+500](https://tex.z-dn.net/?f=55x%3D35x%2B500)
solve for x
![55x-35x=500](https://tex.z-dn.net/?f=55x-35x%3D500)
![20x=500](https://tex.z-dn.net/?f=20x%3D500)
![x=25\ rounds](https://tex.z-dn.net/?f=x%3D25%5C%20rounds)
For x=25 rounds the cost to be the same with and without a membership
Just solve until the answers are the same
25 times x plus 30 for John
15 times x plus 50 for Mary
I believe the answer is D
