Question 53971
Projections are that 100 items will cost $10,000 to produce and that 300 items will cost $22,000 to produce.Find the equation that relates to C and X. 
-----------
You have two points: (100,10000) and (300,22000)
The slope is [22000-10000]/[300-100]= 12000/200=60
The form is C=mX+b; you need to find "b".
10000=60(100)+b
10000=6000+b
b=4000
EQUATION:
Cost=60X+4000
