Final answer:
Zoe's final price for the belts, after applying a 10% discount and adding a 10% processing fee, is less than the original price by approximately 0% when rounded to the nearest whole number.
Step-by-step explanation:
Zoe's original price for belts was $24. She receives a 10% discount, which is $2.40, reducing the price to $21.60. The website then applies a 10% processing fee on the discounted price, adding $2.16, making the final price $23.76. To find by what percent Zoe's final price is less than the original price, we calculate the difference ($24.00 - $23.76 = $0.24) and then divide by the original price ($0.24 ÷ $24 = 0.01). This represents a 1% decrease, but when rounded to the nearest whole number, Zoe's belts were less than the original price by 0%.
