Lisa buys last year's best-selling novel, in hardcover, for $22.50. This is with a 25% discount from the original price. What was the original price of the novel?
22.50 = (1-.25)p
Solve for p.
30.00
Well, it seems Lisa got quite the deal! So, let's see. If the final price of the novel after a 25% discount is $22.50, then we can calculate the original price using a little math magic.
Let's call the original price "x." Since Lisa received a 25% discount, she would have paid 75% of the original price. In other words, 75% of x is equal to $22.50.
Mathematically, we can set up the equation: 0.75x = $22.50.
To solve for x, we divide both sides of the equation by 0.75: x = $22.50 / 0.75.
After dividing, we find that the original price of the novel was $30.00. So, Lisa snatched it up for a bargain! Happy reading!
To find the original price of the novel, we need to calculate the amount of the discount and then subtract it from the sale price.
Step 1: Calculate the amount of the discount.
Discount = Original price * 25%
Discount = $22.50 * 0.25
Discount = $5.625
Step 2: Subtract the discount from the sale price to find the original price.
Original price = Sale price + Discount
Original price = $22.50 + $5.625
Original price = $28.125
Therefore, the original price of the novel was $28.125.
To find the original price of the novel, we need to calculate the price after the 25% discount. Here's how you can do it:
1. Start with the discounted price: $22.50
2. Divide the discounted price by (1 - the discount percentage) to find the original price.
- In this case, the discount is 25%, or 0.25 in decimal form.
- So, divide $22.50 by (1 - 0.25) or 0.75.
- Mathematically, it would be: $22.50 / 0.75 = $30.
Therefore, the original price of the novel was $30.
