Given the cost function upper c (x )and the revenue function upper r (x ), find the number of units x that must be sold to break even. upper c (x )equals15xplus24 comma 000 and upper r (x )equals17x.

12,000 units

Step-by-step explanation:

Let's first set the equations straight:

C(x) = 15*x + 24000

R(x) = 17*x

Now to break even, the revenue must be equal to the cost:

C(x) =R(x)

15*x + 24000 = 17*x

24000 = 17*x - 15*x

24000 = 2*x

24000/2 = x

12,000 = x

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

both equations and proportions are better.
