The answer is 24.

if every time he buys an item the pence goes 'down' by one then it is 24 because 100-76=24

it should be 23 as it started off from 99 . so 99-76 = 23

If he bought 1, it costs X.99
If he bought 2, it costs X.98
So, if he bought 24, it costs X.76.

Your idea of "it started off from 99" forgets to include the first item that you bought to get it to .99
