Answer :
Answer:
$780
Step-by-step explanation:
100% - 85% = 15% = 0.15
Let's assume the original price of the sofa is represented by "x."
We have:
0.15x = $117
x = $117 ÷ 0.15
x = $780
So, the original price of the sofa was $780.
The sales tax to the price of the jacket, the total cost is $91.375
To find the original price of the sofa, we need to understand that the sale price of $117 represents 15% of the original price (since 100% - 85% = 15%). Let the original price be P. We can set up the equation: 0.15P = 117 (where 15% is converted to a decimal, i.e., 0.15).
Solve for P:
- 0.15P = 117
- P = 117 / 0.15
- P = 780
Therefore, the original price of the sofa was $780. Similarly, for another example, Emily bought a jacket for $85 and the sales tax is 7.5%. First, find the amount of sales tax:
- Sales tax = 85 * 0.075 = $6.375
Adding the sales tax to the price of the jacket, the total cost is $91.375
