F2 gross margin, percentages queries

Hi,

I have a couple of questions:

1) in the exam kit of Kaplan question 283, it mentions there is a gross profit margin of 25% and the retailer wishes to increase sales within a certain month by $2000 and in the same month increase payables by $3000. Also in the question they have given information of the credit sales for the retailer and receivables. They have asked to calculate the budgeted payment to the supplier. I don’t understand the working. Please could you help.

2) this is a bit of a different question, generally used in the module. Whenever I have seen, for example a question with idle time, and for the amount to be paid for the labour hours including idle time, assume it’s 1000 hours of labour, 20% idle, why do you divide by 0.8 to find the total hours? So 1250 total.

Thanks very much for your help, and for providing the service. And do let me know if you need anything further info.
