3.5 A shep sells ladies' leans at a discount of \( 15 \% \). Nokwal wants to buy a pair of jeans marked at R150. She only has a R100 note in her purse.

Since the shop offers a 15% discount on the jeans marked at R150, we can calculate the sale price by finding 15% of R150, which is R22.50. By subtracting this discount from the original price, we get R150 - R22.50 = R127.50. Unfortunately, Nokwal's R100 note isn’t enough to cover the discounted price of R127.50. She might need to either save up more or look for a pair within her budget. Nokwal's situation highlights an everyday challenge many face: budgeting for purchases. It's a great reminder to always check sale prices and calculate discounts before heading to the till. This way, she can identify exactly how much cash she needs to bring along or explore other options that fit her budget better!
