Final answer:
To calculate the new total price after applying the discounts, subtract 20% from the original price and then subtract 10% from the discounted price. Multiply the final price by the number of games to get the new total price.
Step-by-step explanation:
To calculate the total price after applying the discounts, we need to follow these steps:
1. Subtract 20% from the original price to get the discounted price.
2. Subtract 10% from the discounted price to get the final price.
3. Calculate the total price of the games by multiplying the final price by the number of games.
By following these steps, we can determine the new total price. If the result is $1407, then option a) is correct. If not, then option b) or c) is correct. It depends on the specific discounts applied.
