Please solve this (cpt maths- equations)

92. variable cost=(10400-6800)/(900-300) = 6

now, 6800=6*300+fixed cost

so fixed cost= 5000

eq : y=6x+5000

93. at break even point profit = 0 ie contribuion=fixed cost

so, break even point = fixed cost/contribution

=5000/(8-6) = 2500

94. if profit of 2000 req,

break even point=fixed cost+req profit/contribution

=5000+2000/(8-6) = 3500

95. by above formula

=5000-3000/(8-6)=1000

hope its clear...feel free to ask if prblm persists...

thank you very much!!!!!
