Final answer:
To find the sale price of a $4,700 diamond wedding set at 30% off, calculate 30% of the original price to determine the discount ($1,410), and then subtract this amount from the original price, resulting in a sale price of $3,290.
Step-by-step explanation:
To determine the sale price of the diamond wedding set that is advertised at 30% off, we start by calculating the discount amount. The discount is 30% of the original price of $4,700. To find this, multiply the original price by the discount percentage expressed as a decimal.
Discount Amount = Original Price × Discount Percentage
= $4,700 × 0.30
= $1,410
Next, we subtract the discount amount from the original price to find the sale price:
Sale Price = Original Price - Discount Amount
= $4,700 - $1,410
= $3,290
Therefore, the sale price for the ring set is $3,290.
