Students get a 15% discount off the original prices at the Everything Fluorscent store during its back-to-school sale. Find the amount of discount on fluorescent notebooks originally priced at 7.99.

This question is asking for 15% of £7.99

If you can do it using a calculator, just do this:

15:100 * 7.99

And that would give you the discount which would be £1.20

If you can't do it using a calculator, you would need to break the percentage of 15% into 10% and 5% and work these out seperately:

10% of £7.99 = 0.799 = 80p

5% of £7.99 (half of above answer) = 0.3995 = 40p

= £1.20

So, to conclude, the amount of discount would be £1.20

(So the notebooks would now cost £6.79)
