Question

A discount voucher offering 15% off is used to pay a bill. After using the voucher, the bill is reduced to £36.72. How much was the bill before applying the voucher discount code.

Answer 1

£91.80

Explanation:

You first have to think, what is 15% of £36.72?

To do this, simply divide 100 by 3672, as we converted £36.72 to pence.

So 3672/100= 36.72. Then we multiply it by 15, which gives us 550.8

We then convert it back to pounds.

After you work that out you will get an answer of £55.08

We then add £55.08 to £36.72 and that will give us the answer, which is...

£91.80

OR

A quicker way is 15/100 of £36.72. Add the answer to £36.72= £91.80
