There is a fixed cost of $4325 in starting a widget business and it also costs $24 to produce each widget. Write a function to describe the total cost of producing x number of widgets.

4325+24x

Step-by-step explanation:

Fixed cost ($4325) is constant and does not vary with the number of widgets produced,

also, for every unit of widget the price increases by $24

If C(x) is the cost function then it should be expressed as

C(x)=4325+24x

A. 5x^2 − 2x − 24 = 0

Step-by-step explanation:

height = 5b-2

b =x

We can rewrite the height as

h = 5x-2

We know the formula for area of a triangle

A = 1/2 bh

A =1/2 x * (5x-2)

Distributing the x

A=    1/2 (5x^2 - 2x)

We know A =12

12 = 1/2 (5x^2 - 2x)

Multiply each side by 2

12*2 = 2*1/2 (5x^2 - 2x)

24 = 5x^2 - 2x

Subtract 24 from each side

24-24 = 5x^2 - 2x-24

0 = 5x^2 - 2x-24
