Jika Endah membeli 2 potong baju, sebuah tas sekolah, dan sepasang sepatu, maka harga yang harus dibayar Endah adalah ....

Solution

Let's analyze the image and calculate the total price Endah has to pay.

The table contains the price and discount for three items:

  1. Baju (Clothes) - Price: Rp 200,000, Discount: 50%
  2. Tas Sekolah (School Bag) - Price: Rp 150,000, Discount: 30%
  3. Sepatu (Shoes) - Price: Rp 140,000, Discount: 40%

Endah buys:

  • 2 pieces of Baju (Clothes)
  • 1 Tas Sekolah (School Bag)
  • 1 pair of Sepatu (Shoes)

Step-by-step calculation:

  1. Baju (Clothes):

    • Price: Rp 200,000
    • Discount: 50%
    • Discounted price = 200,000×(10.50)=200,000×0.50=Rp100,000200,000 \times (1 - 0.50) = 200,000 \times 0.50 = Rp 100,000
    • For 2 pieces: 100,000×2=Rp200,000100,000 \times 2 = Rp 200,000
  2. Tas Sekolah (School Bag):

    • Price: Rp 150,000
    • Discount: 30%
    • Discounted price = 150,000×(10.30)=150,000×0.70=Rp105,000150,000 \times (1 - 0.30) = 150,000 \times 0.70 = Rp 105,000
  3. Sepatu (Shoes):

    • Price: Rp 140,000
    • Discount: 40%
    • Discounted price = 140,000×(10.40)=140,000×0.60=Rp84,000140,000 \times (1 - 0.40) = 140,000 \times 0.60 = Rp 84,000

Total cost:

200,000+105,000+84,000=Rp389,000200,000 + 105,000 + 84,000 = Rp 389,000

The total amount Endah has to pay is Rp 389,000, which matches option D.

Answer: D. Rp 389,000
