Determine the amount of the discount.
This is done by multiplying the normal price by the percentage of the discount, which is 0.35 in decimal form:
Discount = $1200 × 0.35 = $420
Next, to find the sale price, you subtract the amount of discount from the normal price of the bed:
Therefore, the sale price of the bed after a 35% reduction is $780.
