ai.) Let the number of units sold be x, then
57x = 18x + 7800
57 - 18x = 7800
39x = 7800
x = 7800/39 = 200
Therefore, Break-even point in units is 200 units
ii.) Break-even point in dollars = 57 x 200 = $11,400
iii) Break-even point as a percent of capacity = 200/500 x 100 = 40%
c) If fixed costs are reduced to 7020, then
57x = 18x + 7020
39x = 7020
x = 180
d.) If the sellinn price is increased to $78, then
78x = 18x + 7800
78x - 18x = 7800
60x = 7800
x = 7800/60 = 130
