The revenue function for a bicycle shop is given by R(x)=x⋅p(x) dollars where x is the number of units sold and p(x)=200−0.4x is

amid [387]

Answer:

maximum revenue is 25000

Step-by-step explanation:

The revenue function for a bicycle shop is given by R(x)=x⋅p(x)

Given $p(x)= 200-0.4x$

$R(x)=x \cdot p(x)$

Plug in p(x) in R(x)

$R(x)=x \cdot 200-0.4x$

$R(x)=200x-0.4x^2$

Now find out the vertex using formula x=-b/2a

a= -0.4, b=200

$x=\frac{-b}{2a} =\frac{-200}{2(-.4)} =250$

Plug in 250 for x in R(x)

$R(x)=200x-0.4x^2$

$R(x)=200(250)-0.4(250)^2=25000$

So maximum revenue is 25000

The son is 22 years younger than his father, in 4 years the father is 3 times as old as the son. How old are father and son now?

Ganezh [65]

Step-by-step explanation:

Let the son's present age be x years

$\therefore$ Father's present age = (x + 22) years.

Four years after:

Son's age = (x + 4)

Father's age = (x + 22 + 4) =(x + 26) years.

According to the given condition:

Father's age = 3 times the son's age

$\therefore \: x + 26 = 3(x + 4) \\ \therefore \: x + 26 = 3x + 12 \\ \therefore \: 26 - 12= 3x - x \\ \therefore \: 14= 2 x \\ \therefore \: x = \frac{14}{2} \\ \huge \red{ \boxed{ \therefore \: x = 7}} \\ \\ \implies \: x + 22 = 7 + 22 \\ \huge\red{ \boxed{ \therefore \:( x + 22)= 29}}$

Hence, now :

Father's age = 29 years

Son's age = 7 years.

Let us move to the next part of the question:

Let y years ago father's age was 12 times his son.

y years ago

son's age = (7 - y) years

Father's age = (29 - y) years

$\therefore\: 29 - y = 12(7 - y)\\\\\therefore\: 29 - y = 84 - 12y\\\\\therefore\: 12 y - y = 84 - 29\\\\\therefore\: 11y = 55\\\\\therefore\: y = \frac{55}{11}\\\\\huge\orange{\boxed {\therefore\: y = 5}}$

Thus, 5 years ago father's age was 12 times than his son.
