Let's break it down step by step:

1. The original price of an item is 100%.
2. The first discount is 30%, so the price after this markdown is:
   $100\% - 30\% = 70\%$
3. The store then offers an additional 60% off on the new price (not the original). This means you pay only 40% of the remaining 70%:
   $70\% \times 40\% = 0.7 \times 0.4 = 0.28 = 28\%$
4. So, you end up paying 28% of the original price.

1. What would be the final price if the original item costs $50?
2. If an item originally costs $120, how much do you save after both discounts?
3. What happens if an additional 10% off is applied after the second discount?
4. How does this compare to a single 70% discount?
5. If tax is 8% on the final price, how much do you actually pay?

Tip:

Always apply sequential percentage discounts step by step—do not add them together directly!
