Final answer:
To find 10 percent off of $10.35, you convert 10% to a decimal (0.10), then multiply by $10.35 to get the discount ($1.035, rounded to $1.04), and subtract the discount from the original price to get the sale price ($9.31).
Step-by-step explanation:
To calculate what's 10 percent off of $10.35, you first need to convert the percentage to a decimal. The word "percent" means "per hundred", so 10 percent is expressed as 0.10 in decimal form.
Next, multiply the original price by the decimal:
(Original Price) x (Decimal Percentage) = (Discount Amount)
So,
$10.35 x 0.10 = $1.035
That means the discount amount is $1.035, which is usually rounded to the nearest cent. Therefore, the discount is approximately $1.04.
Finally, to find the new price after the discount, subtract the discount amount from the original price:
(Original Price) - (Discount Amount) = (Sale Price)
$10.35 - $1.04 = $9.31
