Re: Discount

hi NightHawk

Welcome to the forum.

So for part a, you did something like 80 - 10% of 80.

For part b: this could mean get 5% and take it off twice.  You'll get the same answer as part a.

So the questioner probably means:

First step answer = 80 - 5% of 80.

Then (first step answer) - 5% of (first step answer).

This won't reduce the price by so much as the second step is working out 5% of a smaller amount.

Hope that helps.
