SOLUTION: How would I write the linear cost function.
12 units cost $445; 50 units cost $1585.
I know the answer is c(x)=3x+85
But I can't figure out how they go the 3 or the 85.

I know the answer is c(x)=3x+85
But I can't figure out how they go the 3 or the 85. Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! I don't know either since neither point works in the equation, =$121 =$235

The linear function would look like,
With the first point,
1.
With the second point,
2.
Subtract eq. 1 from eq. 2 to eliminate b.
Did you mean 30 instead of 3 in your solution above?
Then use either equation to solve for b.

Just to verify, =$445 =$1585
