You are buying a TV and a TV stand. The TV original cost was $469 but is on sale for 40% off. The TV stand is being sold for 5% more than what the store paid for it. The store bought 34 stands for $500.00. Then you have to pay 7.25% sales tax on your purchase. How much is your TOTAL COST?

Step-by-step explanation:

If you're saving 40% on the TV, you are still paying 60% of the cost.  Therefore, the TV on sale is 469(.60) which totals $281.40

Now for the stands.  If the store paid 500 for 34 stands, then the cost for the store per stand was 500/34 or $14.71 per stand.  But the store is charging you 5% more than what they paid.  You are paying 100% of what the store paid, plus an extra 5%, so you are paying 105% more than what the store paid.  Therefore, the cost of your stand is 14.71(1.05) which totals $15.45.  The cost of the 2 items together, before tax, is $281.40 + $15.45 which is a subtotal of $296.85.  You are paying 100% of that cost plus another 7.25% for tax, so what you are paying is 107.25% of the cost of both your items.

296.85(1.0725) = $318.37
