Step-by-step explanation:1. Determine the original price: - The new price is ₱7600.00, and the increase is ₱1200.00. - Original price = New price - Increase - Original price = ₱7600.00 - ₱1200.00 - Original price = ₱6400.002. Calculate the percentage increase: - Percentage increase = (Increase / Original price) × 100% - Percentage increase = ( ₱1200.00 / ₱6400.00 ) × 100% - Percentage increase = 0.1875 × 100% - Percentage increase = 18.75%So, the percentage increase in the price of the TV set is 18.75%.
