Xiaoming went to a restaurant and ordered the following dishes:

  • A portion of Schnitzel (breaded and fried pork cutlet) for 32 euros
  • A portion of Hungarian Goulash with bread for 35 euros
  • A portion of Spaghetti Bolognese for 32 euros

The total cost was 99 euros.

After paying, he discovered a promotional offer at the restaurant:

  • There was a special voucher for Schnitzel, which cost 28 euros and could be used directly.
  • Additionally, he could purchase a 50-euro discount voucher for 44.9 euros, which could be applied to the total bill.

Xiaoming found this deal worthwhile, so he bought the Schnitzel voucher and the 50-euro discount voucher. The restaurant refunded his original 99-euro payment in full, allowing him to use the vouchers for payment instead.

How much did Xiaoming actually need to pay in the end?

Calculating final outlay

Let's break this down! Xiaoming initially paid 99 euros and later bought two vouchers: a 28-euro Schnitzel voucher and a 44.9-euro discount voucher. The restaurant refunded his original 99 euros and he used the vouchers for the payment. So, the total cost of the vouchers he bought adds up to 72.9 euros (28 + 44.9). That's the amount he ended up spending on the meal overall.

Clarifying final payment

So, Xiaoming’s total meal costs 99 euros, but after he buys the vouchers, it changes. The Schnitzel voucher, which costs 28 euros, covers the 32-euro Schnitzel dish. The 50-euro discount voucher reduces the remaining bill by 50 euros. After using both vouchers, the remaining food costs (Goulash and Spaghetti) add up to 67 euros, and the discount brings it down to 17 euros. Therefore, he ends up paying an additional 17 euros after applying the vouchers.

Final payment analysis

Xiaoming spent 28 euros for the Schnitzel voucher and 44.9 euros for the discount voucher. After using the vouchers, his remaining bill is 17 euros (after the discount). He ultimately pays an additional 17 euros, so his total out-of-pocket cost is 28 + 44.9 + 17 = 89.9 euros. The 99 euros he originally paid is refunded, so it doesn't count as additional spending. Therefore, his net total cost for the meal is 89.9 euros.

Let's break down the process step by step:

  1. Original Order and Payment

    • Dishes Ordered:
      • Schnitzel: 32 euros
      • Hungarian Goulash with bread: 35 euros
      • Spaghetti Bolognese: 32 euros
    • Total: 32 + 35 + 32 = 99 euros
    • Xiaoming pays 99 euros, but later the restaurant refunds this entire amount.

  2. The Vouchers Purchased:

    • Schnitzel Voucher: Costs 28 euros and covers the Schnitzel dish (which originally cost 32 euros).
    • 50-euro Discount Voucher: Costs 44.9 euros and can be applied to the total bill.

  3. Re-calculating the Bill with the Vouchers:

    • Since he now uses the Schnitzel voucher, the Schnitzel dish is “paid for” using the voucher instead of the 32-euro price.
    • The remaining dishes (Goulash and Spaghetti Bolognese) total 35 + 32 = 67 euros.
    • The 50-euro discount voucher is then applied to the remaining 67-euro total, reducing it to 67 – 50 = 17 euros.

  4. Total Out-of-Pocket Cost:

    • Voucher Costs:
      • Schnitzel voucher: 28 euros
      • 50-euro discount voucher: 44.9 euros
      • Subtotal for vouchers: 28 + 44.9 = 72.9 euros
    • Remaining Payment at Restaurant: 17 euros
    • Final Total: 72.9 (vouchers) + 17 (remaining bill) = 89.9 euros

Thus, after the refund and applying the vouchers, Xiaoming ultimately had to pay 89.9 euros.
