1. ## cost problem function

Your assistance in checking what I have correcting me and assisting in my empty space is mucho appreciated!!

The computer shop sells computers. The shop has fixed costs of $1500 per week. Its average cost per computer is$649 each, and the average selling price is $899 each. A) Writer the linear cost function C(x) = 649x + 1500 ?? B) Write the linear revenue function R(x) = px --> 899* (x) C) Find the cost selling 37 computers a week 37*?? D) Find the revenue from selling 37 computers E) Find the break even point 2.

A) Writer the linear cost function
C(x) = 649x + 1500 ??
yes, this is the cost per week

B) Write the linear revenue function
R(x) = px --> 899* (x)
yes

C) Find the cost selling 37 computers a week
37*??
huh?

you found the formula for cost in part (a), did you not? why don't you use it?

D) Find the revenue from selling 37 computers
look back at part (b)

E) Find the break even point
this is where C(x) = R(x)

solve for x

3. ## ahhh, thank you!!

Could you break down "E" for me? Sometimes I swear I learn by the "baby step" method!

Thanks again!

break even means the cost is the same as the revenue, so you neither make money, nor lose money. just set the two formulas equal to each other and solve for x

$649x + 1500 = 899x$ ............this is cost = revenue
