Jawab:

Toko indah

Penjelasan dengan langkah-langkah:

baju = 75.000

celana = 80.000

toko rame = (75.000 – (75.000 x 25%)) + (80.000 – (80.000 x 10%))

= (75.000 – 18.750) + (80.000 – 8.000)

= 56.250 + 72.000

= 128.250 (Paling mahal)

toko damai = (75.000 – (75.000 x 20%)) + (80.000 – (80.000 x 15%))

= (75.000 – 15.000) + (80.000 – 12.000)

= 60.000 + 68.000

= 128.000

toko senang = (75.000 – (75.000 x 15%)) + (80.000 – (80.000 x 20%))

= (75.000 – 11.250) + (80.000 – 16.000)

= 63.750 + 64.000

= 127.750

toko indah = (75.000 – (75.000 x 10%)) + (80.000 – (80.000 x 25%))

= (75.000 – 7.500) + (80.000 – 20.000)

= 67.500 + 60.000

= 127.500 (Paling murah)
