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

AB Computer company must sell 116 computers to break even.

Step-by-step explanation:

Hi, to break even the cost and revenue must be the same, so, both equations must be equal.

Mathematically speaking:

C(x)=R(x)

145+1/4x= 1.5x

Solving for x:

145 = 1.5x-1/4x

145=1.25x

145/1.25 =x

116=x

So, AB Computer Company must sell 116 computers to break even.

Feel free to ask for more if needed or if you did not understand something.

problem:

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

f(5/2) = 10/3

i hope this !

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
