Step 1
Step 2
How much more was the average monthly expenditure on housing in 2015 than in 2005?
Answer
To find out how much more was spent on housing in 2015 than in 2005, we check the values on the bar chart. In 2015, the expenditure was £560, while in 2005 it was £480.
Thus, the difference is:
egin{align*} 560 - 480 = 80 \end{align*}
So, the average monthly expenditure on housing in 2015 was £80 more than in 2005.
Step 3
What percentage of this was spent on transport?
Answer
In 2005, the total average monthly expenditure was £1200. According to the bar chart, the amount spent on transport in 2005 was £240. To calculate the percentage spent on transport:
egin{align*}
ext{Percentage} = rac{240}{1200} imes 100 = 20
\end{align*}
Therefore, 20% of the total average monthly expenditure in 2005 was spent on transport.
