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:
Ronnie's annual salary this year = $38,850
Explanations:
Ronnie's annual salary last year = $37,000
Percentage increase in Ronnie's salary = 5%
Increase in Ronnie's salary = 5% of 37000 = 5/100 x 37000
Increase in Ronnie's salary = $1850
Ronnie's annual salary this year = Ronnie's annual salary last year + Increase
Ronnie's annual salary this year = $37000 + $1850
Ronnie's annual salary this year = $38,850

Answer:
14.25 ft
Step-by-step explanation:
1 inch of the model represents 18 inches of the real car. The car's dimensions are 18 times larger than the model's dimensions. Multiply the model dimension by 18 to find the corresponding real dimension.
9 1/2 * 18 = 9.5 * 18 = 171
The actual car is 171 inches long.
Now we need to convert 171 inches to ft.
1 ft = 12 in.
Since we want to eliminate inches and end up with feet, we divide both sides by 12 in.
(1 ft)/(12 in.) = 1
The conversion factor is (1 ft)/(12 in.) to go from inches to feet.
171 in. * (1 ft)/(12 in.) = 14.25 ft
Answer: 14.25 ft
