Cost-Volume-Profit Assumptions.....help!

mdc

I am being asked for the 3 assumptions used in cost-volume-profit analysis - does anyone know? I cannot find the details anywhere in my notes or the study texts!

Thanks

1. What do you assume in terms of the price charged per unit?
2. What do you assume in terms of each variable cost per unit?
3. What do you assume in terms of the total fixed cost (irrespective of units sold)?
