Required information
The Hard Rock Mining Company is developing cost formulas for management planning and decision-making purposes.
The company's cost analyst has concluded that utilities cost is a mixed cost, and he is attempting to find a base that
correlates with the cost. The controller has suggested that tons mined might be a good base to use in developing a cost
formula. The production superintendent disagrees; she thinks that direct labor-hours would be a better base. The cost
analyst has decided to try both bases and has assembled the following information:

1. Using the least-squares regression method, estimate the variable utilities cost per ton mined and the total fixed utilities cost per
quarter. Express these estimates in the form Ya+bX. (Round the Variable cost per unit to 2 decimal places and Fixed Cost to the
nearest whole dollar amount.)
