Final answer:
The price of a video game console after a 20% markdown from the original price of $399.50 at Games Galore is $319.60.
Step-by-step explanation:
To calculate the price of a video game console at Games Galore after a 20% markdown, we must first determine how much money is being taken off the original price. A 20% discount on a $399.50 item can be found by multiplying the original price by the discount percentage in its decimal form (20% = 0.20).
Discount Amount = Original Price × Discount Rate = $399.50 × 0.20
Discount Amount = $79.90
Now, we subtract the discount amount from the original price to find the new sale price:
New Sale Price = Original Price - Discount Amount
New Sale Price = $399.50 - $79.90 = $319.60
