Final answer:
To calculate the sale price of a playground slide with a 40% discount off its original price of $710, multiply $710 by 0.40 to get the discount amount of $284. Then subtract $284 from $710 to find the sale price, which is $426.
Step-by-step explanation:
The student is looking to find the sale price of a playground slide that is marked at 40% off its original price of $710. To do this, we calculate the discount amount by finding 40% of $710 and then subtract that amount from the original price to determine the sale price.
To find 40% of $710, we convert the percentage to a decimal by dividing 40 by 100, which is 0.40. Then multiply $710 by 0.40:
Discount Amount = Original Price × Discount Rate
Discount Amount = $710 × 0.40
Discount Amount = $284
Now, subtract the discount amount from the original price to get the sale price:
Sale Price = Original Price - Discount Amount
Sale Price = $710 - $284
Sale Price = $426
