1) The Sweater Shack is offering a 20% discount on sweaters. If the regular price of a sweater is $15.00, what is the discount? What is the sale price?
Step 1: Find the discount amount
Discount = 20% of $15.00
= 0.20 × 15.00 =
$3.00
Step 2: Find the sale price
Sale Price = Regular Price – Discount
= 15.00 – 3.00 =
$12.00
✔ Answer:
- Discount:
$3.00
- Sale Price:

2) After a 15% off sale, some jeans were $11.50. How much were the jeans before the sale?
Let the original price be
x.
After a 15% discount, the price is 85% of the original (since 100% - 15% = 85%).
So:
$$
0.85x = 11.50
$$
Solve for x:
$$
x = \frac{11.50}{0.85} ≈ 13.53
$$
✔ Answer: The jeans originally cost
$13.53 (rounded to nearest cent).
