The linear equation which relates p and c is c = 600 + 30p
c = total cost
c = total cost p = number of parts
Cost per part = $30
Monthly fixed cost = $600
Total cost = Fixed cost + variable cost
Varibale cost = number of parts × cost per part = 30p
Hence. Total cost :
Total cost = $600 + 30p
Therefore,
c = 600 + 30p
