Given the cost function, c(x), and the revenue function, r(x), find the number of units x that must be sold to break even.
c(x) = 4000x + 88,000
r(x) = 12,000x

Equate the functions and then solve for x.

Hope this helps.

11 units must be sold to break even.

Step-by-step explanation:

Profit is expressed as Revenue - Cost. Break even is the point at which there is neither profit nor loss. This means that profit would be zero. Therefore,

Revenue - cost = 0

Revenue = cost

Given the cost function, C(x) to be

C(x) = 4000x + 88,000

and the revenue function, R(x) to be

R(x) = 12,000x, the number of units x that must be sold to break even would be

4000x + 88000 = 12000x

12000x - 4000x = 88000

8000x = 88000

x = 88000/8000 = 11

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35
