Can you explain the other stuff you wrote down so I can help? Can you put the stuff on a line so I can understand?
Answer:
Hey there!
We can write this equation, where x is the hourly rate and y is the fixed fee.
4x+y=270
7x+y=420
4x+y=270
-7x-y=-420
-3x=-150
x=50
4(50)+y=270
200+y=270
y=70.
The fixed fee is G. $70.
Let me know if this helps :)

21/sin41=x/sin115 = 29
For Question 3,
15 ?
__ = ____
120 100
