Let x represent the quantity of child tickets sold and y represent the quantity of adult tickets sold
Child (x): $45 each
Adult (y): $85
Cost equation: 45x + 85y = 72000
Quantity equation: x + y = 1000
45x + 85y = 72000 → 45x + 85y = 72000
-45( x + y = 1000) → <u>-45x - 45y = -45000</u>
40y = 27000
y = 625
Quantity equation: x + y = 1000 → x + (625) = 1000 → x = 375
Answer: 375 child tickets and 625 adult tickets
44x
Step-by-step explanation:
For a wave:
y = A sin (2π/T x − φ) + B
A is the amplitude,
T is the period,
φ is the phase shift,
and B is the offset.
The given wave is:
f(x) = -5 sin(x + 2π) − 4
So the amplitude is -5, the period is 2π, and the phase shift is -2π.
