Question 56998:    Business and finance. In planning for a new item, a manufacturer assumes that 
the number of items produced x and the cost in dollars C of producing these items 
are related by a linear equation. 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 C and x  
Thank you

You can  put this solution on YOUR website! 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 C and x  
----------------- 
You have two points to work with: (100,10000) and (300,22000) 
You want C=mx+b and need to know m and b: 
m= [22000-10000]/[300-100]=12000/200=60 
Then: 
10000=60(100)+b 
10000=6000+b 
b=4000 
EQUATION: 
Cost=60x+4000
