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.

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.

Re: fixed cost

It should be y = 30 x + 700

Re: fixed cost

Hi;

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

Yes agree, you are exactly correct. Y intercept is the fixed cost.
