Homework due tonight at 12. Could really use the help. I don't understand how to calculate variable cost and the fixed cost when. Like what formulas need to be used.

Harbor Images has collected the following cost data for various levels of activity: Month Images Created Total Cost August 5,350 $ 5,570 September 7,100 $ 6,190 October 7,450 $ 8,014 November 3,850 $ 4,990 a. Using the high-low method, determine the variable cost per image created and the total xed cost. (Round your variable cost to 2 decimal places.) Variable Cost - Per Image Fixed Cost - Per Month b. Estimate the total costs when 5,850 images are created. (Do not round your intermediate calculations.) :|
