text: if i want to buy a router at best buy and it costs 49.99 plus a 8.25% sales tax, whats the total? i live in texas. i find the guys answer about the router hilarious, ok just take 49.99 and multiply it by 1.0825        thats the easiest way, or you can do it the slow old school way of multiplying by .0825 and then adding it to the original thing, either way it will be the same answer..  please go learn math, its good for you.
