So you have 8 digits (number available) to form 3 digit numbers (number selected).
Using the formula
where a is the number of available digits, P is the permutation function and c is the number of digits to be selected.
The number of three digit numbers that can be formed =
= 336
<span> O R
</span>By using the formula
where a is the number of available digits and c is the number of digits to be selected.<span>
</span>⇒

</span>⇒
<span>
</span>⇒ Permutation = 336<span>

If we want to calculate the full prize we need to calculate how much the tax was:
420* 17
%=420*
=420*
=21*
=73.5
so this is how much the tax was.
and the full prize is the cost of the ring and the tax: 420+73.5=493.5
so that's how much the buyer will pay
420* 17
so this is how much the tax was.
and the full prize is the cost of the ring and the tax: 420+73.5=493.5
