Month Meals Served Total Costs
July 3,500 $20,500 August 4,000 22,600 September 4,200 23,350 October 4,600 24,500 November 4,700 25,000 December 4,900 26,000 I have gotten the fixed costs as$4.29.
26500-20500/4900-3500 = 6000/1400 = 4.29

I am not able to find the variable costs.
20500-3500*4.29 = 20500-15015=5485
26000-4900*4.29 = 26000-21021=4979
