Ziegler Inc. has decided to use the high-low method to estimate the total cost and the fixed and variable cost components of the total cost. The data for various levels of production are as follows:

Units Produced			Total Costs
1,755			$273,780
3,330			328,840
5,655			425,880

a. Determine the variable cost per unit and the total fixed cost.

Variable cost: (Round to the nearest dollar.)	$ per unit
Total fixed cost:	$

b. Based on part (a), estimate the total cost for 2,670 units of production.

Total cost for 2,670 units:
