Answer:
In 3y-24, 3 is the greatest common factor.
3y-24
=3(y-8)
12% = 12/100 = 0,12
0,12 x x = 9
x = 9/0.12
x = 75
9 is 12% of 75
Answer: 16
its just x plus 1/3 of x. This is harder to find so youre probably not expected to find it this way.
Actual way to solve it.
set up proportion.
= 
cross multiply
3 x x = 3x
12 x 4 = 48
48 = 3x
divide by 3 to get x
48 / 3 = 16
x = 16

Answer:
The Answer is: Lower Level seats = 150. Upper level seats = 200.
Step-by-step explanation:
Start with two known equations:
1 - the number of Lower Level times 35 + the number of Upper level times 25 = the total dollar amount of $10,250.
35L + 25u = 10250
The number of both types of tickets = 350
L + u = 350
Solve for u:
u = 350 - L
Substitute and solve for L, Lower level seats:
35L + 25(350 - L) = 10250
35L + 8750 - 25L = 10250
10L + 8750 = 10250
10L = 1500
L = 150
There are 150 Lower Level seats.
u = 350 - L
Subtract to get the number of upper level seats:
u = 200
Proof:
35(150) + 25(200) =
$5,250 + $5,000 = $10,250
