Hamburger 1.80lbs sausage is 1.90lbs
1.80+ 1.80+ 1.90=$5.50
People who purchased good seats will be labeled as a
people who purchased poor seats will be labeled as b
therefore...
5a + 2b = 660
a + b = 210
Now, all that has to be done is for the system to be solved.
-2(a+b=210)
5a + 2b = 660
-2a - 2a = -420
3a=240
a= 80
*3 people purchased good seats.
Now we can plug that number in
5(80) + 2b = 660
400 + 2b = 660
2b = 260
b = 130
*130 people purchased poor seats
Answer:
30 feet is represented by 3 3/4 inches on the drawing
Step-by-step explanation:

Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = ((- 2, - 3 ) and (x₂, y₂ ) = (x, 5x + 9 )
