Suppose that the dollar cost of producing x appliances is c(x)=1000+ 90x- 0.2x 2
Aleksandr [31]

Answer:

Step-by-step explanation:

Given that the dollar cost of producing x appliances is

c(x)=1000+ 90x- 0.2x^2

A) Average cost can be obtained by dividing c(x) by units = x

i.e. average cost = \frac{1000}{x} +90-0.2x

B) Marginal cost = dC/dx = 90-0.4x

When x=140 marginal cost = 90-0.4(140)\\=34

C) We calculate

c(140) = =1000+90(140)-0.2(140^2)\\\\=9680

c(141) = =1000+90(141)-0.2(141^2)\\\\\\=9713.80

Marginal cost = difference = 33.80

Same as 34 shown in marginal cost.

jonathan goes to th store and purchases 3 pencils for 0 .28 each, and x number of erasers for 0.38each write an expression that
Anestetic [448]

Keywords

linear equation, variables

Step 1

Define the <u>variables</u>

Let

x-----> number of erasers

y-----> total cost

we know that

y=3(0.28)+(0.38)x

y=0.84+(0.38)x  ------> this is the <u>linear equation</u> that represent the situation

therefore

the answer is

y=0.84+(0.38)x
