Question

 A bedroom set that normally sells for $1565 is on sale for 40% off. If sales tax rate is 2%, what is the total price of the bedroom set if it is bought while on sale?

Answer 1

Keep in mind that percentages always add 1 (under in decimal form) or 100% (when given in percentages)

There are TWO ways to figure this out...I will show ONE way (but see the note in the middle)

You can figure out what the discount (of the ORIGINAL price) is...that's the 40% of the $1565 BUT the final sale price is the original price MINUS the discount. Remember percentages is a number over 100.

Discount is 40% of the original price

$1565 x (⁴⁰/₁₀₀) =$626

Final price is the original price minus the discount

Final sale price is $1565 - $626 = $939

Note: The final sale price is (60%) of the original price, $1595 x ( ⁶⁰/₁₀₀ ) = $939

The tax on the final sale price = $939 x 2% = $939 x (²/₁₀₀) = $18.78

The FINAL price for the bedroom set (incl tax) = $939 + $18.78 = $957.78 or ($939 x 1.02)

Hope this helps...

Hey Jaila!

So for this problem, the set is first bought for $1565 while it is 40% off, so we have to find how much it is purchased for while at this discount:

1565 * .60

939

The set costs $939 after the discount, but we still have to pay the sales tax on top of the price, so now we multiply the price by 1.02, or we add 2%:

939 * 1.02

957.78

So the price afterwards is $957.78
