Some tips and help to do these pages.
This chapter of maths is quite hard. We are all trying our best so that’s all you can do too. If you are finding this difficult have a look under “Special Ed Resources” and then click the tab “Maths” there are slightly easier pages to do there.

This page takes a lot of time. You might decide to just do A.
A
(a) If you know the cost of 2 litres divide by 2 to find the cost of 1 litre.
(b) Find the cost of 1 egg in every shop – e.g. 6 eggs cost €2. Each egg is €2 ÷ 6 = 0.50c
(c) Read the offers very carefully.
(d) Shane bought 3 yoghurts. He will only receive the offer on 2 of the yoghurts.
(e) Find the cost of 100g of sausages in each shop. Top tip: there are 1000g in 1kg
(f) Use some of the information you’ve already figured out e.g. price per egg and per 100g of sausages.

VAT – VAT is money that is paid to the government when we buy goods and services. For different items the government charge different amounts. Use a calculator if you want to.
1. Have a look at the table and see how much VAT is being charged on each item.
Example
(a) The television in the shop costs €350.00. The government charge 23% VAT on televisions. I know this because I looked at the table at the top of the page. I need to find 23% of €350.00. 23% as a fraction is 23/100. Divide by the bottom and multiply by the top.
350.00 ÷ 100 = 3.5
3.5 x 23 = 80.5 (VAT)
350.00 + 80.5 = €430.50
1 (C) This one is a little bit different. This time they have given us the price including VAT. When I look at the top of the page I can see the VAT charged on books is 0%. This means that the book costs €11.99 with VAT and without VAT. But what happens if it is not 0%? Let’s take a look at 1 (f).
1 (f). A bottle of coke including VAT costs €2.46. The VAT on coke is 23%. So it in order to find the cost price (the price without VAT) we must let
€2.46 = 123%
2.46 ÷ 123 = 1%
0.02 = 1%
2.00 = 100% (Cost Price)

Interest is just like profit that we have looked at before. Let’s have a look at number 1.
1. Price = 7,000
Interest is 6%.
Find 6% of 7,000. (6% = 6/100 = 0.06)
7000 x 0.06 = 420
7000 + 420 = 7,420
