How many computers must the ab computer company sell to break even? let x be the number of computers.
cost function: c (x) = 145 + 1/4x
revenue function: r (x) = 1.5x

You break even if you spend exactly as much as you gain. In other words, if the cost and the revenue are the same:

Subtract 0.25 from both sides:

Divide both sides by 1.25:

So, they must sell 116 computers to break even. If they sell less, they'll lose money. If they sell more, they'll start making profit.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
