ii / Change data

It was found that the unit cost prices for some of the items were wrongly quoted. The correct unit cost prices are as follow: o Burger - RMI .50 0 Fried chicken wing - RM0.85 With these changes in price, do you think the club can still achieve the target of RM500? Adjust the unit cost prices as above. Save your adjusted spreadsheet as budget2 Was your prediction correct?

Actual sale

During the actual fair, what if some of the items were not completely sold? Do you think the club can still reach the

target of RM500?

Insert a column in between columns E on and F: select column E. Click . . -

. - the menu bar, then select Enter the column head as Quantity Sold. Enter the quantities sold in this new column F. You will need to change the formula for Sale. The formula for Sale for Cola is now quantity sold x unit selling price. Copy this formula to the rest of the cells in column H. Use the SUM function to find the total actual sale. Was your prediction correct?
