The marked price of the ring given the cost as 8740 inclusive of 15% tax and discount of 5% is $7,283.3.
<h3>Marked price</h3>
- Cost of the gold ring = $8740
- Tax = 15%
- Discount = 5%
- Marked price = x
8740 = x + (15% of x) + (5% of x)
8740 = x + (0.15x) + (0.05x)
8740 = x + 0.15x + 0.05x
8740 = 1.20x
x = 8740 / 1.20
x = 7283.33333333333
Approximately,
x = $7,283.3
