b) fixed cost=b in y-intercept form variable cost, dependent on n=m in y-intercept form Knights: fixed=1250 variable=25
Legions: fixed=995 variable=30
c) insert 45 into n for both formulas:
Knights: 25*45+1250=1125+1250=2375
Legions: 30*45+995=1350+995=2345
d)With 45 guests the Legion's Banquett Hall is cheaper, but due to the higher variable cost this changes with a few more people. calculate break even point: difference in variable cost=5 -> per person the cost difference will decrease by this much if another person joins current price difference: 2375-2345=30 30/5=6 -> if there are 6 additional guest (total= 51) they will cost the same if there are more than 6 additional guest (total >51) the knight's banquett will be cheaper.
