A $310 suit is marked down by 20%. Find the sale price.
First, we need to find the amount of the discount.
Discount = Original Price * Discount Rate
Discount = $310 * 0.20
Discount = $62
Next, subtract the discount from the original price to find the sale price.
Sale Price = Original Price - Discount
Sale Price = $310 - $62
Sale Price = $248
Therefore, the sale price of the suit is $248.
