### fixed cost

I thought that I had the formula for this problem down but I am not coming up with an answer anywhere close. Can somone please assist?

Suppose a manufacturer finds that the cost y of producing x units is given by the formula of the form y=mx+b. If is costs \$1,300 to produce 20 units and \$1,750 to produce 35 units, what is the fixed cost?

Doesn't b determine the fixed cost?

### Re: fixed cost

If I am remembering it right, the y intercept is the fixed cost. You are correct that is b.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

### Re: fixed cost

Then I am doing something incorrectly because I am coming up with y=30x+1310 and that is not one of my options.

It should be y = 30 x + 700

Hi;

If you show me your work, I can try to figure that out.
