use of best fit, y= a+bx, a= fixed cost, b= variable cost per unit

b= n

(i) Using regression analysis calculate the line of best fit through the data and interpret your values of a and b.

(ii) Forecast the time it would normally take to deliver an order for a distance of 5 miles.

(b) Using a report format, identify and appraise the sources of finance available to the Board of Directors of Dragon Limited.
