A case study in the importance of percentages: so how much is the UK duty on Wine?
It’s £2.16 on a bottle of still wine and it’s £2.77 on a bottle of sparkling wine – and that’s before 20% VAT. Retailers calculate their margin on that additional cost, so the difference then becomes even greater. UK wine drinkers are already the second most heavily taxed in Europe, only beaten by Ireland. It is unfortunate that wine drinkers are perceived as an easy target in order to reap more tax revenue for successive governments.
With the average selling price of a bottle of wine in the UK at £5.39, this means that around 65% of the cost of that bottle is now consumed in tax. In Britain, just 60p is the cost of the wine itself!

MSC's year 9 homework for the weekend: collect some data from an online source (this can be anything at all but must have at least 20 data points, e.g. the number of citizens in 20 EU countries, the number of olympic medals earned by 20 different countries), and make a grouped frequency table. For your data, estimate the mean, find the class for the median, and estimate the modal class. Make a comment on what you think the statistics mean. Present all of this on a sheet of A4 paper.

MSC's homework for Monday evening. Do the following ten questions. Copy them out and then write them up properly.
1. Increase 345 by 23%. 2. Decrease 2454 by 14% 3. My £32 salary increases by 1% and then 0.5% the following year. How much am I paid in two years' time? 4. A car is reduced by 65% and then a further 4%. What is the overall percentage reduction? 5. The postVAT cost of a TV is £278. VAT is 17.5%. What is the preVAT cost? 6. 35% of students at a school are only children. 70 children have siblings. How many children are in the school? 7. Increased 56 by 780%. 8. The population of Lalaland has grown by 2.3% over the last year, to 1 200 000. What was the population last year? 9. What is the hardest thing to understand about percentage questions? 10. Describe a common error when doing percentages and how to avoid it.
