If the cost is a function depending on the number of sections, how much will 200 sections cost?

It will cost $7439.

Step-by-step explanation:

We first find the rate of change between consecutive points.  Between the first two,

m = (1889-409)/(50-10) = 1480/40 = 37

Between the second two points,

m = (4664-1889)/(125-50) = 2775/75 = 37

Since the rate of change is the same between points, this is a linear situation.

Writing the equation of the line in point-slope form, we have

y - 409 = 37(x - 10)

Using 200 as x,

y - 409 = 37(200 - 10)

y - 409 = 37(190)

y - 409 = 7030

Adding 409 to both sides,

y = 7030 + 409 = 7439

step-by-step explanation:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
