Answer:<u> </u><u>$1.75</u>
Solve for:
What price would result in the most revenue?
Step-by-step explanation:
Let the price of one donut = 1 + 0.05x
Let the # of donuts he can sell = 500 - 10x
Revenue,




Revenue is maxed when x = 15
When the revenue is maxed,

Therefore the best price for this scenario is $1.75
I believe the answer is "A"
To convey as an algebraic expression simply break down the statements and use any variable to represent the number in the sentence.
10 • x^2 = 40x
10x^2 = 40x
10x^2 - 40x = 0
10(x^2 - 4x) = 0
X(x - 4) = 0
X = 0
X - 4 = 0
X = 4.
Here are two possibilities of what the number can be, but because it is a nonzero number, I believe it would be 4.
Hola!
x = 7 , x = -7
Explicación:
Comienza restando 15 en cada lado:

Usted obtiene:

Ahora divide ambos lados por 2:

Usted obtiene:

Como la ecuación está al cuadrado, tendrás que hacer:

que te da: 
Entonces:

Answer:
30
Step-by-step explanation:
