Jawab:
$ 9400
Penjelasan:
Diketahui:
Potongan 30% = (100-30)% = 70% = ⁷/₁₀
harga sebelum diskon = n
Rumus yang diperoleh =
⁷ⁿ/₁₀
Dipotong lagi 30% = ⁷/₁₀ bagian dari ⁷ⁿ/₁₀
Rumus yg diperoleh
7(⁷ⁿ/₁₀)/10
Harga akhir = $ 4606, maka
4606 = 7(⁷ⁿ/₁₀)/10
7(⁷ⁿ/₁₀) = 46060
⁷ⁿ/₁₀ = 46060/7
⁷ⁿ/₁₀ = 6580
7n = 65800
n = 65800/7
n = 9400
Harga sebelum diskon = $ 9400
