A boutique handmade umbrella factory currently sells 37500 umbrellas per year at a cost of 7 dollars each. In the previous year

slega [8]

Answer:

$302,500

Step-by-step explanation:

If cost (C) = $7, then Sales (S) = 37,500 units

If cost (C) = $15, then Sales (S) = 17,500 units

The slope of the linear relationship between units sold and cost is:

$m=\frac{37,500-17,500}{7-15}\\m= -2,500$

The linear equation that describes this relationship is:

$s-s_0 =m(c-c_0)\\s-17500 =-2500(c-15)\\s(c)=-2500c + 55,000$

The revenue function is given by:

$R(c) = c*s(c)\\R(c)=-2500c^2 + 55,000c$

The cost at which the derivative of the revenue equals zero is the cost that yields the maximum revenue.

$\frac{d(R(c))}{dc}=0 =-5000c + 55,000\\c=\$11$

The optimal cost is $11, therefore, the maximum revenue is:

$R(11)=-2500*11^2 + 55,000*11\\R(11)=\$ 302,500$

$\boxed { \boxed { a_n = a_1 + d(n - 1)}}$

$a_{14} = -33 , a_{15} = 9,$

$a_{14} = a_1 + d(14 - 1) = -33$
$a_1 + 13d = -33$

$a_{15} = a_1 + d(15 - 1) = 9$
$a_1 + 14d = 9$

So the two equations:
$a_1 + 13d = -33$ ----------------- ( 1 )
$a_1 + 14d = 9$ ----------------- ( 2 )

(2) - (1) :
$d = 42$ ----------------- (Sub into 1)

$a_1 + 13(42) = -33$
$a_1 + 546= -33$
$a_1 = -33 - 546$
$a_1 = -579$

$\boxed { \boxed { a_n = -578 + 42(n - 1)}}$
