R(x) = 60x - 0.2x^2
The revenue is maximum when the derivative of R(x) = 0.
dR(x)/dx = 60 - 0.4x = 0
0.4x = 60
x = 60/0.4 = 150
Therefore, maximum revenue is 60(150) - 0.2(150)^2 = 9000 - 4500 = $4,500
Maximum revenue is $4,500 and the number of units is 150 units
Answer:
no
Step-by-step explanation:
4x -3 = 16
x=19/4
4(x-3) = 16: Distribute the number in the parenthesis with 4 and you get:
4x-12=16
x=7
4x-12=16 is not the same as 4x-3=16
Therefore they do not have the same solution.
Answer:
X=0
Step-by-step explanation:
Answer:
The answer is D.
Step-by-step explanation:
3x*3x = 9x^2
3x*2= 6x
5*3x=15x
5*2=10
6x+15x=21x
9x^2+21x+10

30% of 70 is 21.
Yes, it's right, but the answer is 21, not 21%.
