Mr Stagoll also performed a calculation in respect of the comment in the franchise document to the effect that most "sites" required sales figures of approximately $7,000 per week to break even. This showed that, based upon sales of $7,000 per week and a 50 per cent mark-up on cost, a gross profit of $121,334 would be derived, from which it might be concluded that the operating expenses of the store at that level of turnover would be this sum. Mr Stagoll next produced a calculation which again assumed annual sales of $520,000 and a cost of sales of $346,667 (allowing for a 50 per cent mark-up). From the resulting gross profit of $173,333 he deducted annual expenses based upon a break-even turnover of $7,000 per week which, as I have said, amounted in all to $121,334. He then deducted a further sum of $52,000 which, he said, catered for the cost of the increased turnover, being an extra $3,000 per week (the sum of $52,000 being derived by multiplying the sum of $121,334 by 10, dividing it by 7 and substracting the sum of $121,334 from the result). This produced a net loss of $1.
