This is a system
x is the number of advanced tickets sold
y is the number of same day tickets sold
once you label your variables then write the equations
x+ y = 45 total tickets sold
20x + 25y = 1050 money taken in
multiply the top equation by -20 and the x will drop out
-20x - 20y = -900
20x + 25y = 1050. Add the equations result is
5y = 150, divide by 5 ,
y or same day tickets cost $30
substitute 30 into first equation
x + 30 = 45 therefore x = 15

Answer: Option B, x ≥ 121
Step-by-step explanation:
We start with the inequality:
√x ≥ 11.
First, we can square each side of the inequality, to get:
(√x)^2 ≥ 11^2
And we know that:
√(x^2) = (√x)^2 = x
Then:
x ≥ 11^2
x ≥ 121
So we only need to have x equal or larger than 121.
The correct option is B.
