Answer:To find the percentage decrease:Original Price = $3,000Sale Price = ₱800 (assuming PHP, Philippine Peso)First, convert ₱800 to USD (approximate):₱800 ≈ $16 (using exchange rate: 1 USD ≈ 50 PHP)Now, calculate the decrease:Decrease = Original Price - Sale Price= $3,000 - $16= $2,984Percentage Decrease = (Decrease ÷ Original Price) × 100= ($2,984 ÷ $3,000) × 100≈ 99.47%So, the price decreased by approximately 99.47%.Note: This calculation assumes the exchange rate is correct and the sale price is in Philippine Pesos.
