Percentages

[dylanfanatic]

Am useless at maths. My 500g block of farm butter cost £3-50p, and has since increased to £3-85p over the past four weeks. Anybody know what percentage increase that is? I haven't a clue how to work it out!
Thanks a lot

10 per cent

It has increased by 35p which is one tenth of £3.50

The increase is 35p or £0.35.

The original cost was £3.50.

35p is 10% of £3.50

[Tilly2]

35p increase
35p is 10% of £3.50

To explain the working:

the increase is 35p (£3.85 - £3.50). To find the increase you divide that 35p by the original price (350p - remember to keep the units the same) and multiply the result by 100.

So, 35 divided by 350 equals 0.1. Multiply that by 100 and the answer is 10.

When you look at 35p and £3.50 you can see straight away that the first is one tenth of the second which equals 10%.
