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
840			$78,120
1,660			115,790
2,240			121,520

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 1,110 units of production.

Total cost for 1,110 units:
