If an item costs $90 and is on sale for 30% off, what will the sale price be?

• A. $63
• B. $72
• C. $75
• D. $81

Answer: (B)

To find the sale price of an item that costs $90 and is on sale for 30% off, you first need to calculate the amount of the discount. This involves finding 30% of the original price. First, calculate 30% of $90: \[ 30\% = \frac{30}{100} \times 90 = 0.30 \times 90 = 27 \] This means the discount amount is $27. Next, subtract the discount from the original price to find the sale price: \[ Sale Price = Original Price - Discount = 90 - 27 = 63 \] Therefore, the sale price is $63. The other options do not reflect the correct calculations based on the given discount percentage. The calculations confirming a sale price of $63 come from accurately determining the discount amount and subtracting it from the original price. Thus, the correct answer is $63.
