Final answer:
To calculate the discounted price of the TV, multiply the original price by 25% to find the discount amount and subtract it from the original price. The TV, after the 25% discount, will cost $337.50.
Step-by-step explanation:
To determine the cost of the TV after a 25% discount, we first calculate the discount amount by multiplying the original price ($450) by 25%.
- Calculate the discount: $450 × 0.25 = $112.50
- Subtract the discount from the original price: $450 - $112.50 = $337.50
So, the TV will cost $337.50 after the discount.
