Question

The cost of manufacturing a molded part is related to quantity produuced during production run when 100 parts cost 500 dollars and 500 cost 1900 dollaers wat is cost per unit

Answer 1

The cost of manufacturing a molded part is related to the quantity produced during a production run in addition to a fixed set-up cost. When 100 parts are produced, the cost is $1300. When 300 parts are produced, the cost is $2300.

You probably are asked to generate an equation that relates parts produced
to cost.
You have 2 points (100,1300) and (300,2300)
-----
slope = (2300-1300)/(300-100) = 1000/200 = 5
------
Form: cost = slope(# of parts) + b
solve for "b" which is the set-cost for the operation.
1300 = 5(100) + b
b = 1300-500
b = 800
--------
Equation:
C(x units) = 5(x units) + 800
OR
C(x) = 5x + 800
