Here is a spreadsheet created by the organisers of a concert. They have assumed that 400 people will attend the concert. They have also assumed that each member of the audience will purchase 2 snacks and 2 drinks during the concert. If these assumptions are correct, their profit will be $710. A B C D Tickets Drinks Snacks Souvenirs Programmes Electricity $20 $15 $3 $2 $40 Price Quantity per concert goer Total income $16,000 Income $1,600 $2,400 $8,000 $6,000 $34,000 $650 Paid out $22,000 $860 $880 $5,000 $2,400 $1,500 $33,290 Total outgoings $710 Profit/Loss Estimated audience size Performers Drink supplies Snack supplies Venue hire Souvenir supplies Programme supplies A number of factors could affect the amount of profit. • The audience size might be higher than the organisers estimated. • Members of the audience might not buy 2 snacks and 2 drinks. • The cost of souvenir supplies might change. Explain how the organisers could use what-if analysis to see the effects of these three factors on their profit. You should refer to specific cells from the spreadsheet in your answer. The organisers wish to achieve a larger profit. By explaining what each step requires them to do, describe how the organisers would use goal seek to find the size of the audience needed to make a profit of $5000. You should refer to specific cells from the spreadsheet in your answer. Include in your answer a reason why the result might not be satisfactory.
