The equation that can be used to represent the number of albums at which the profit would be equal for the two methods of selling her album is -0.03x² + 4x + 6000 = 0
<h3>How to solve equations in the form of no quadratic</h3><h3 />
- x = the number of albums sold
- y = the profit in dollars,
Method 1, y = -0.05x² + 12x - 8000
Method 2, y = -0.02x² + 8x - 2000
-0.05x²2 + 12x - 8000 = -0.02x²2 + 8x - 2000
- 0.05x² + 0.02x² + 12x - 8x - 8000 + 2000 = 0
-0.03x² + 4x - 6000 = 0
where,
a = -0.03
b = 4
c = -600

In the given question it is already given that the original price of the ticket for the football game is "p". It is also given that the $63 is the discounted price of the ticket. $12.50 is the discount given on the original price of the ticket. These information's are enough for solving the given question.
We can write the equation as
p - 12.50 = 63
p = 63 + 12.50
= 75.50
So the original price of the ticket for the football game is $75.50
4t=r
a=pir^2
sub 4t for r
a=pi(4t)^2
a=pi16t^2
a(t)=16pi(t^2)
A. a(t)=16pi(t^2)
B. sub 4 for t
a(4)=16pi4^2
a(4)=16pi16
a(4)=16*16*3.14
a(4)=803.84 square units
A. a(t)=16pi(t^2)
B. 803.84 square units
Answer:
4x+7*500=11300 is the formula. (there are many formulas this might not be correct) (x is the number of students)
1925 students
Step-by-step explanation:

AN ASSESMANT?!?!?!?
500*7=$3500 for the adults
11,200-3500=7700
so 7700/4=1925
