Milk Delivery Problem

 

 

This part is for you to read.

Before buying its new computer, the dairy kept its records like this:

House Number Mon Wed Fri Week-end Total Cost

12 ´ 32p = £3.84

13 ´ 32p = £4.16

Notice that 1 pint of milk costs 32p.

The dairy could use a spreadsheet to keep records like this.

The spreadsheet would work out the total and the cost automatically.

If someone changed their order the spreadsheet would up-date the calculations.

In the total column you told the spreadsheet to add up the 4 numbers that said how much milk is delivered. You did not type in the number.

But the number appears in the spreadsheet.

In fact, the Total column and the Cost column should have all of the numbers showing correctly.

Now we can change some of the numbers to see the spreadsheet automatically up-date the Total and the Cost.

Now Do This

The family who live at house number 13 change their Wednesday order to 4 pints.

Change that entry in the spreadsheet.

Write down their new Total and their new Cost.

Now make these changes and write down the new Total and the new Cost.

1. The family at number 13 change their week-end order to 6 pints.

2. The family at number 13 change their Monday order to 4 pints.
