Hey lads, im doing A2 Economcis and Business, and whilst this is and extremely easy unit it was a very hard paper but it was still fairly straight forward. The first one was 14% Operating profit margin, as you put operating profit/ total revenue x100= 13.975%
I put market differentiation for he Beck undies question, lower mobile prices due to another competitor joining he phone industry in Yahoo, and the second calculation with contributions was 140 a it said what was the contribution to the charity (i.e. the profits sent to them so you need to take off the £20 fixed costs)
for the liability question I talked about it allowing owners to take more risks with their retained profit to expand as they can only lose what they put into the business- and the profit they earned themselves
