# hey! help over here? s.o.s?

a store advertised a discount of 15% 0ff the listed price of every item.find the total cost,including a 6% sales tax of a stereo that has a price tag of \$400

Relevance

Since your discount is 15%, you will be paying 100% - 15% = 85% of the listed price.

\$400 x 85% = \$340 before tax

Then, since you're paying 6% tax on that, plus 100% of the discounted price, you're really paying 106% of the discounted rate.

\$340 x 106% = \$360.40 final price

• The price of the stereo is 400

The price of the discount is 15% ( 15/100) or (0.15)

Therefore the cost of the stereo is 85% ( 100%-15% ) or (0.85)

Multiply

400 times 0.85 = 340.00

Taxes are 6%

Tax is usually on the non-sale price so use 6% of 400

0.06 times 400 = 24.00

Is there State taxes or County taxes, or luxury taxes?

If not add the cost and the taxes

340.00 + 24.00 = \$364.00

Are there yearly service contracts involved in this sale?

From this information that is your cost, but be careful. Sometimes in very small print it says with a 2 year service contract, or only with trade in, or other phrases like that.

Best wishes and good luck

• 400*(1-15%)=340

This is the price after discount.because the discount is 15%,which make the price should be (1-15%)which is 85% of the price shown.

then you calculate 340+340*6%=360.4

This is the total cost.

• Price tag=\$400

discount@15%=\$60

discounted price=\$340

tax@6%=\$20.40

cost=\$360.40

• list price = 400

15%off -> 15*400/100=60

so price after discout = 340

6%sales tax -> 6*340/100 = 20.4

so cost = 340+20.4 = \$360.4

• Take the discount off of the purchase price, then tax it!

• 400 * .15 = 360 after discount

Then 360 * .06 = 338.40 after tax

• 15% off means you pay 85% or .85

400*.85*(1.06)=\$360.40
