Final answer:
The sale price of the video game originally costing $55 with a 30% discount is $38.50. The discount amount is calculated by multiplying the original price by the discount rate (0.30), resulting in $16.50. After subtracting this amount from the original price, we arrive at the sale price.
Step-by-step explanation:
The question involves calculating the sale price of a video game that is being sold at a discount. The original cost of the video game is $55, and it is on sale for 30% off. To determine the sale price, we perform the following calculation:
Step 1: Calculate the discount amount
30% of $55 is calculated by multiplying 55 by 0.30:
Discount amount = 55 × 0.30
= $16.50
Step 2: Subtract the discount from the original price
Subtract the discount amount from the original price:
Sale price = $55 - $16.50
= $38.50
Therefore, the sale price of the video game after applying the 30% discount is $38.50.
