Answer: P(x) = -3x^2 + 49x - 105
Step-by-step explanation:
The revenue accrued is the total income from sales or services rendered irrespective of the cost of purchase, production or rendering of the service. It means that revenue is the sum of cost and and profit.
From the information given, the revenue is expressed as a function,
Revenue = R(x)=x(65-3x) = 65x - 3x^2
The cost function is expressed as
C(x)=105+16x
Revenue = Profit + Cost
Therefore,
R(x) = P(x) + C(x)
65x - 3x^2 = P(x) + 105+16x
P(x) = -3x^2 + 65x - 16x - 105
P(x) = -3x^2 + 49x - 105
20% percent refers to the rate
So to find 20% off of $125 you have to multiply the rate by the original price and then subtract that number from the original price
First you have to make the percent into a decimal. To do that you have to move the decimal point over to the left two times or divide by 100:
20/100= .20
So the equation would be:
.20 • 125= 25
Now you have to subtract from the original number:
125-25=100
So the answer would be that the stereo would cost 100 with the 20% off sale
Different parallelograms require different ways of solving so theorems tell you how each parallelogram can be solved
Answer:
Calculate the slope in the four intervals with the formula
m = (f(b) - f(a)) / (b - a) slope in Intervall [a; b]
m1 = (3 - 0) / (2 - 0) = 1.5
m2 = (11 - 3) / (4 - 2) = 4
m3 = (23 - 3) / (6 - 2) = 5
m4 = (23 - 11) / (6 - 4) = 6
between x = 4 and x = 6 is the correct answer.
