Short Answer 
To find the final price of jeans after a 15% discount on the $150 marked price, a discount of $22.50 is calculated, resulting in a final price of $127.50. However, since Nolwazi only has a $100 note, she cannot purchase the jeans as the final price exceeds her payment capability.
Step 1: Calculate the Discount Amount
To determine how much the jeans will cost after a 15% discount on the marked price of 150 dollars, we first need to calculate the discount amount. Use the following process:
- Convert the percentage to decimal: 15% = 0.15
- Multiply this decimal by the original price: 0.15 ‚à öo 150 = 22.50 dollars
Step 2: Determine the Final Price After Discount
Now, we subtract the discount amount from the original price to find the discounted price of the jeans. Follow these steps:
- Original price: 150 dollars
- Discount amount: 22.50 dollars
- Final price = Original price – Discount amount: 150 – 22.50 = 127.50 dollars
Step 3: Assess the Payment Method
Since Nolwazi intends to pay using only 100 dollar notes, it’s essential to evaluate if this is feasible given the final price. Here’s the breakdown:
- The final price is 127.50 dollars
- Nolwazi’s available payment option is a single 100 dollar note
- Since 127.50 dollars exceeds 100 dollars, Nolwazi will not be able to buy the jeans using only 100 dollar notes.
