We can also use averages to give us a clue of likely future events – if we know that we made £17.50 a day on average selling lemonade in a week then we can assume that in a month we would make: So we can say that on average we made £17.50 a day. What we can work out is the daily average: £122.50 ÷ 7 (Total money divided by 7 days). We don’t know how much money was made each day, just the total at the end of the week. In this example, assume that £122.50 is made by selling lemonade in a week. Sometimes we may know the total of our numbers but not the individual numbers that make up the total. In the first row of the table above we know that twenty-one people get paid a salary of £20,000, instead of working with £20,000 work with 20:Ģ1 x 20 = 420 then replace the ,000 to get 420,000. You can ignore the ,000's when calculating as long as you remember to add them back on at the end. The salaries, in the example above, are all multiples of £1,000 – they all end in ,000.
