Final answer:
The subject is a mathematical calculation of a 20% discount on plants. The complete question is not provided, but a method for calculating the sale price after the discount is explained, using a formula to find the discounted amount and subtract it from the original price.
Step-by-step explanation:
The question seems to concern a mathematical calculation involving a percentage discount on plants during a clearance sale at a nursery. However, the question appears to be incomplete as the percentage value is provided but the actual question is missing. Assuming the student is asking how to calculate the new price after the discount, here's a general approach:
If a plant is originally priced at P dollars, and the markdown is 20%, then the discount amount would be 20% of P. To calculate the discount, you use the formula:
Discount = (Percentage Discount / 100) × Original Price
This would give you:
Discount = (20 / 100) × P = 0.20 × P
You would then subtract this discount from the original price to get the sale price:
Sale Price = Original Price - Discount
Sale Price = P - (0.20 × P)
Sale Price = P(1 - 0.20)
Sale Price = 0.80 × P
This shows that the plant will now cost 80% of the original price. For an actual calculation, the student would need to provide the original price of a plant.
