Question

A company has discovered that it costs $16 to produce 2 widgets. $18 to produce 4 widgets. $48 to produce 10 widgets. Whats the total cost for 6 widgets?

Answer 1

It would cost $24 to produce 6 widgets.

Explanation:

If you turn the information into points, you can use those three points to find the parabolic function for the graph (it's y=(x squared over 2) -2x +18.) All you have to do then is find where 6 widgets lines up with the graph.
