The question asks for the final price of an item after a 40% discount is applied to a $75 item.

To find the price after the discount:

1. Calculate the discount amount:
   40% of $75 = $0.40 \times 75 = 30$

2. Subtract the discount from the original price:
   $75 - 30 = 45$

So, the final cost of the item after the 40% discount is $45.

2. How do you calculate a 25% discount on any item?
3. If tax is added after the discount, how do you include that in the final price?
4. How much would the item cost if there was a 10% additional discount after applying the 40% discount?
5. How can you calculate the original price if only the discounted price and percentage discount are known?

Tip: When calculating discounts, multiplying the original price by $1 - \text{discount percentage}$ in decimal form gives the final price directly.
