The cost to produce one laptop computer is $750 plus a one- time fixed cost of $130,600 for research
and development. The revenue received from selling one laptop computer is $1375.
(a) Write a formula that gives the cost of producing x laptop computers.
(b) Write a formula that gives the revenue R from selling x laptop computers.
(C) How many laptop computers need to be sold to yield a positive profit?

Step-by-step explanation:

(a) C = 750x + 130,600

(b) R = 1375x - 130,600

(c) Y > 1375x - 130,600

95 x 1375 = 130625

Profit: $ 25

ab will be equal to

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
