Answer:
We save 16.18 dollars.
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
If you still don't get how I got my answer, just ask more questions to me! =)
