To determine which expressions represent the percent decrease in the price of the video game, we can use the formula for percentage decrease:

$\text{Percent Decrease} = \frac{\text{Original Price} - \text{New Price}}{\text{Original Price}} \times 100$

Given:

• Original price = $60
• Sale price = $48

The decrease in price is: $\text{Decrease} = 60 - 48 = 12$

Now, applying the percentage decrease formula: $\text{Percent Decrease} = \frac{12}{60} \times 100 = 20\%$

Now, let's check the given expressions:

• A. $\frac{60 - 48}{60} \times 100$: This matches the correct formula for percent decrease, so A is correct.

• B. $\frac{60 - 48}{48} \times 100$: This uses the new price in the denominator, which is incorrect for percentage decrease.

• C. $\frac{12}{48} \times 100$: This incorrectly uses the new price ($48) instead of the original price ($60) in the denominator.

• D. $\frac{12}{60} \times 100$: This correctly represents the percent decrease, so D is correct.

• E. $\frac{60 - 48}{60 + 48} \times 100$: This is not correct, as it uses the sum of the original and new prices in the denominator.

Final Correct Answers:

• A and D
