Question

A Coffee table was $129.99 and on sale for 20% off. The sales tax is 8.5%. How much do we save?

Answer 1

Answer:

Step-by-step explanation:

Discount = 20% of 129.99

$=\frac{20}{100}*129.99\\\\=25.998$

= $26

Price after discount = 129.99 - 26 = $103.99

Tax = 8.5% of 103.99

$=\frac{8.5}{100}*103.99\\\\=8.83915$

= $8.84

Selling price including tax = 103.99 + 8.84

                                           = $112.83

Amount saved = 129.99 - 112.83

                        =$ 17.16

Answer 2

Answer:

We save 16.18 dollars.

Step-by-step explanation:

First, I did calculations on how much money there would be with the discount.

129.99 times 0.2 equals 25.1 [So with the discount, I got 25.1 dollars off.]

129.99 - 25.1 = 104.89 [so with the discount, I just have to pay 104,89, now,]

Now, I did the calculations WITH the SALES TAX.

104.89 times 0.085 equals 8.92 [ so tax is actually 8.92 dollars.]

104.89 + 8.92= 113.81 [ SO, with TAX, the table costs 113.81.]

Now I see how much money I have saved.

104.89 - 113.81 = 16.18
