revenue = N*p

costs = N*u+f

where N is the number of cards sold, and p is the selling price, u the unit costs, and f the fixed costs. Then the breakeven point is when:

revenue=costs,

or:

N*p=N*u+f

Use new selling price of p'=1.1*pb) If demand increases and the selling price of the sound cards increase 10%. what is the new break even point?

Thanks in advance for any replies
