Final answer:
The subject is Mathematics for Middle School level. To find the percent discount, subtract the sale price from the original price and divide by the original price, multiply by 100. The percent discount of the TV Matthew bought is 24%.
Step-by-step explanation:
The subject of this question is Mathematics, and it involves calculating the percent discount given on the purchase of a TV. Matthew bought a TV for $440.80, which was listed at its original price of $580. To find the percent discount, we first calculate the amount discounted by subtracting the purchase price from the original price, which gives us $580 - $440.80 = $139.20. Next, we calculate the percent discount by dividing the amount discounted by the original price and then multiply by 100 to convert it to a percentage: ($139.20 ÷ $580) × 100 = 24%. Therefore, the percent discount of the TV is 24%, which corresponds to option A.
