Question 1
11600
A factory produces calculators. The least-squares regression line for the cost of production \((C)\) as a function of the number of calculators \((n)\) is given by \(C = 500 + 7.85n\).
This function is considered accurate for \(100 \le n \le 1000\). Find the cost to produce 250 calculators and decide if this is interpolation or extrapolation.
