Question P6 An average is a total
Today’s problem — free all day, every step. Every day has one.
A bakery recorded its sales over 5 days: $42, $48, $55, $51 and $44. What was the average daily sales amount over the 5 days?
Answer
$48 a day.
Turn the average back into a total before doing anything with it.
In this one. An average is the total shared equally, so it lands between the low days and the high days — $48 is below the best day's $55, not equal to it.
The word 'average' appears alongside a group being split into two parts, or two separate journeys or trips being combined into one overall figure.
Children average two averages directly, such as averaging two speeds or two group averages, without weighting by how many, or how long, each part actually covers.
