Answer:
A = -68.75p +2906.25
Step-by-step explanation:
We can solve for m and b using the given values of A and p.
1600 = m·19 +b
2150 = m·11 +b
Subtracting the second equation from the first, we have ...
-550 = 8m
m = -550/8 = -68.75
Substituting this into the first equation gives ...
1600 = 19·(-68.75) +b
b = 1600 +1306.25 = 2906.25
The desired linear equation is ...
A = -68.75p +2906.25

Revenue will be maximized at the price that cuts attendance to half the value when the price is 0, about $21.14.
This does not need the quadratic formula since there are no variables to begin with:
62-46+4 = 0
20 = 0.
And 20 does not equal 0 so both sides aren't equal.
Soooo not much to do with this question.
You can't use the distributive property on the numbers 48 and 72 because the numbers aren't in an equation.
<span> by using calculator, these are the answers:
√20 = 4.47213595499958
√18 = 4.24264068711928
but without calculator,
√20 = √(4x5)
= √4 x √5
= 2 x √5
= 2√5
√18 = √(9x2)
= √9 x √2
= 3 x √2
= 3√2 </span>
