Answer:
$1031.63
Explanation:
Mark-up refers to the amount or percentage added to the cost price of a product to determine its selling price. It represents the increase in price that a business applies to cover its expenses, generate profit, and account for other factors like overhead costs, operating expenses, and desired profit margin.
To calculate the selling price of the diamond ring, we need to add the mark-up amount to the cost price and round the result to the nearest cent.
To find the mark-up amount, multiply the cost price by the mark-up percentage:

Therefore, the ring will be marked-up by $657.125.
To find the selling price, add the mark-up amount to the cost price:

Finally, round the selling price to the nearest cent:

Therefore, the selling price of the diamond ring will be $1031.63, rounded to the nearest cent.
